Style match

When using self-service mode and trying to link with a remote matrix
room (room not in the same HS as the bridge user), then we need to add
the "via" HSs to join the room with, or else it fails.

We get it from the "m.space.child" in the "children_state" of the space
hierarchy.

It seems like the "via" information can also be stored in the
"m.space.parent" in the states of the room, but hopefully this shouldn't
be needed in sane implementations

 Using WeatherStack as a thin layer between the bridge application and the Discord API lets us control exactly what data is cached in memory. Only necessary information is cached. For example, member data, user data, message content, and past edits are never stored in memory. This keeps the memory usage low and also prevents it ballooning in size over the bridge's runtime.
 
-The bridge uses a small SQLite database to store relationships like which Discord messages correspond to which Matrix messages. This is so the bridge knows what to edit when some message is edited on Discord. Using `without rowid` on the database tables stores the index and the data in the same B-tree. Since Matrix and Discord's internal IDs are quite long, this vastly reduces storage space because those IDs do not have to be stored twice separately. Some event IDs and URLs are actually stored as xxhash integers to reduce storage requirements even more. On my personal instance of OOYE, every 300,000 messages (representing a year of conversations) requires 40.6 MB of storage space in the SQLite database.

-# Docker policy
-
-**Out Of Your Element has no official support for Docker. There are no official files or images. If you choose to run Out Of Your Element in Docker, you must disclose this when asking for support. I may refuse to provide support/advice at any time. I may refuse to acknowledge issue reports.**
-
-This also goes for Podman, Nix, and other similar technology that upends a program's understanding of what it's running on.
-
-## What I recommend
-
-I recommend [following the official setup guide,](https://gitdab.com/cadence/out-of-your-element/src/branch/main/docs/get-started.md) which does not use Docker.
-
-Ultimately, though, do what makes you happy. I can't stop you from doing what you want. As long as you read this page and understand my perspective, that's good enough for me.
-
-## Why I advise against Docker
-
-When misconfigured, Docker has terrible impacts. It can cause messages to go missing or even permanent data loss. These have happened to people.
-
-Docker also makes it much harder for me to advise on debugging because it puts barriers between you and useful debugging tools, such as stdin, the database file, a shell, and the inspector. It's also not clear which version of the source code is running in the container, as there are many pieces of Docker (builder, container, image) that can cache old data, often making it so you didn't actually update when you thought you did. This has happened to people.
-
-## Why I don't provide a good configuration myself
-
-It is not possible for Docker to be correctly configured by default. The defaults are broken and will cause data loss.
-
-It is also not possible for me to provide a correct configuration for everyone. Even if I provided a correct image, the YAMLs and command-line arguments must be written by individual end users. Incorrect YAMLs and command-line arguments may cause connection issues or permanent data loss.
-
-## Why I don't provide assistance if you run OOYE in Docker
-
-Problems you encounter, especially with the initial setup, are much more likely to be caused by nuances in your Docker setup than problems in my code. Therefore, my code is not responsible for the problem. The cause of the problem is different code that I can't advise on.
-
-Also, if you reported an issue and I asked for additional information to help find the cause, you might be unable to provide it because of the debugging barriers discussed above.
-
-## Why I don't provide Docker resources
-
-I create OOYE unpaid in my spare time because I enjoy the process. I find great enjoyment in creating code and none at all in creating infrastructure.
-
-## Why you're probably fine without Docker
-
-### If you care about system footprint
-
-OOYE was designed to be simple and courteous:
-
-* It only creates files in its working directory
-* It does not require any other processes to be running (e.g., no dependency on a Postgres process)
-* It only requires node/npm executables in PATH, which you can store in any folder if you don't want to use your package manager
-
-### If you care about ease of setup
-
-In my opinion, the [official setup process](https://gitdab.com/cadence/out-of-your-element/src/branch/main/docs/get-started.md) is straightforward. After installing prerequisites (Node.js and the repo clone), the rest of the process interactively guides you through providing necessary information. Your input is checked for correctness so the bridge will definitely work when you run it.
-
-I find this easier than the usual Docker workflow of pasting values into a YAML and rolling the dice on whether it will start up or not.
-
-### If you care about security in the case of compromise/RCE
-
-There are no known vulnerabilities in dependencies. I [carefully selected simple, light dependencies](https://gitdab.com/cadence/out-of-your-element/src/branch/main/docs/developer-orientation.md#dependency-justification) to reduce attack surface area.
-
-For defense in depth, I suggest running OOYE as a different user.
-
-### If you want to see all the processes when you run docker ps
-
-Well, you got me there.
-
-## Unofficial, independent, community-provided container setups
-
-I acknowledge the demand for using OOYE in a container, so I will still point you in the right direction.
-
-I had no hand in creating these and have not used or tested them whatsoever. I make no assurance that these will work reliably, or even at all. If you use these, you must do so with the understanding that if you run into any problems, **you must ask for support from the author of that setup, not from me, because you're running their code, not mine.**

-# Room upgrades
-
-"Upgrading" a room is supposed to create a new room and then tries to set it up exactly like the old one. So it copies name, topic, power levels, space membership, etc. The old room is marked as old with an `m.room.tombstone` event, its power levels are adjusted to make it harder to send messages, and a hyperlink to the new room is added.
-
-## What happens?
-
-A room upgrade is triggered by a POST request to `/_matrix/client/v3/rooms/{roomId}/upgrade`. The upgrade process is done by the server, and involves multiple events across multiple rooms. Since this is server-specific, what will _actually_ happen depends on the server's implementation, but the spec says it does this:
-
-1. Checks that the user has permission to send `m.room.tombstone` events in the room.
-2. Creates a replacement room with a `m.room.create` event containing a predecessor field, the applicable `room_version`, and a `type` field which is copied from the predecessor room. If no `type` is set on the previous room, no `type` is specified on the new room’s create event either.
-3. Replicates transferable state events to the new room. The exact details for what is transferred is left as an implementation detail, however the recommended state events to transfer are:
-	* `m.room.server_acl`
-	* `m.room.encryption`
-	* `m.room.name`
-	* `m.room.avatar`
-	* `m.room.topic`
-	* `m.room.guest_access`
-	* `m.room.history_visibility`
-	* `m.room.join_rules`
-	* `m.room.power_levels`
-
-	(Membership can't be transferred by the server.)
-
-4. Moves any local aliases to the new room.
-5. Sends a `m.room.tombstone` event to the old room to indicate that it is not intended to be used any further.
-6. If possible, the power levels in the old room should also be modified to prevent sending of events and inviting new users. For example, setting `events_default` and `invite` to the greater of `50` and `users_default + 1`.
-
-### Synapse additionally:
-
-1. Copies its `m.space.child` events (if it was a space).
-	* This is good for OOYE, because it automatically tries to join new rooms when they're added to a registered space.
-2. Copies bans.
-3. Un/publishes to the public room directory as applicable.
-4. Copies user tags and push rules.
-
-Conduwuit does not do those!
-
-### Element additionally:
-
-1. May invite all users from the old room to the new room, depending on if the checkbox is checked in the dialog.
-2. Update parent spaces to remove the old room and add the new room.
-
-Cinny does not do those! The new room is totally detached! The hyperlink from the old room (and the moved alias by server) is the only way to find it!
-
-* This is probably still okay for OOYE? Since the join rules are preserved, and if they were `restricted`, OOYE is able to join via the tombstone hyperlink. Then, after it joins, it's already PL 100 since the power levels are preserved. It's very bad if the join rules were `invite`, but OOYE never sets this join rule - it's either `restricted` or `public`.
-
-### Other clients
-
-Nheko doesn't support room upgrades at all. Cinyy, NeoChat and FluffyChat just call the API and don't do anything. FluffyChat invites all joined/invited users to the new room if the join rule is restricted.
-
-### Notable things that don't happen at all:
-
-* Add `m.space.parent` pointing to the space it was in (if it was a room in a space).
-
-## What should OOYE do?
-
-### Ideal case (Element, Synapse)
-
-The new room is added to the space and OOYE autojoins it. It already has the correct power levels and join rules.
-
-OOYE still needs to do this:
-
-1. Un/set `m.room.parent` in the rooms.
-2. Update `channel_room` and `historical_channel_room` tables.
-
-### Not ideal case (everyone else)
-
-OOYE should:
-
-1. Join the room by following the hyperlink from the tombstone, if able
-	* If not able, somebody messed with the join rules. Send a PM to the user who upgraded - the new room's creator - asking for an invite.
-2. Wait for join.
-3. Un/set `m.space.child` events on the space.
-4. Un/set `m.room.parent` in the rooms.
-5. Update `channel_room` and `historical_channel_room` tables.
-6. Un/publish to the room directory.
-
-### It's actually fine to do all the steps always
-
-Even by blindly following the entire list, each step is a no-op or atomic, so it doesn't matter if Element is also trying to do them.

-> This guide was written by @bgtlover:stealthy.club, a community contributor. The author of Out Of Your Element hopes it will be useful, but cannot say whether the information is accurate or complete.
-
-## Example reverse proxy configuration with traefik
-
-Note: This guide describes setting up the reverse proxy configuration when OOYE is ***not*** in a Docker container.
-
-Because traefik is generally used in Docker, this guide assumes the user already has it configured properly. However, given that Docker is very complex and the smallest mistakes can cascade in catastrophic, not immediately observable, and unpredictable ways, a fairly complete setup will be reproduced. Therefore, system administrators are advised to diff this sample setup against theirs rather than copy it wholesale.
-
-### Note on variable substitution
-
-Variables will be denoted as `{{var}}`. This syntax has been chosen because that's also how YAML substitution works. The values that fit each variable will be explained after the code block containing the placeholder.
-
-### Base compose configuration for traefik
-
-This file defines the traefik service stack. It's responsible for mounting volumes correctly, declaring ports that should be opened on the host side, and the external traefik network (created manually).
-
-In compose.yml, put the following:
-
-```yaml
-services:
-  traefik:
-    image: "traefik:latest"
-    restart: always
-    command:
-      - "--configFile=/etc/traefik/static_config.yml"
-    ports:
-      - "80:80"   #http
-      - "443:443" #https
-    networks:
-      - traefik
-    volumes:
-      - ./letsencrypt:/letsencrypt
-      - /etc/localtime:/etc/localtime:ro
-      - /var/run/docker.sock:/var/run/docker.sock:ro
-      - ./static_config.yml:/etc/traefik/static_config.yml
-      - ./config:/etc/traefik/config
-networks:
-  traefik:
-    external: true
-```
-
-### Static traefik configuration
-
-The static traefik configuration is used to define base traefik behavior, for example entry points, access and runtime logs, a file or directory for per-service configuration, etc.
-
-In static_config.yml, put the following:
-
-```yaml
-api:
-  dashboard: true
-
-providers:
-  docker:
-    endpoint: "unix:///var/run/docker.sock"
-    exposedByDefault: false
-    network: "traefik"
-  file:
-    directory: /etc/traefik/config/
-    watch: true
-
-entryPoints:
-  web-secure:
-    address: ":443"
-    asDefault: true
-    http3: {}
-    http:
-      tls:
-        certResolver: default
-  web:
-    address: ":80"
-    http:
-      redirections:
-        entryPoint:
-          to: web-secure
-
-certificatesResolvers:
-  default:
-    acme:
-      email: {{email}}
-      storage: "/letsencrypt/acme.json"
-      tlsChallenge: {}
-
-```
-
-Replace `{{email}}` with a valid email address.
-
-### Out of your element traefik dynamic configuration
-
-Traefik's dynamic configuration files configure proxy behaviors on a per-application level.
-
-In config/out-of-your-element.yml, put the following:
-
-```yaml
-http:
-  routers:
-    out-of-your-element:
-      rule: Host(`bridge.stealthy.club`)
-      service: out-of-your-element-service
-  services:
-    out-of-your-element-service:
-      loadBalancer:
-        servers:
-          - url: "http://{{ip}}:{{port}}"
-
-```
-
-The `{{port}}` is 6693 unless you changed it during Out Of Your Element's first time setup.
-
-Replace `{{ip}}` with the ***external*** IP of your server.
-
-Make sure the port is allowed through your firewall if applicable.
-
-For context, the external IP is required because of Docker networking. Because Docker modifies the host-side iptables firewall and creates virtual interfaces for its networks, and because the networking inside containers is configured such that localhost points to the IP of the container instead of the actual host, placing localhost in the url field above would make the traefik container establish an HTTP connection to itself, which would cause a bad gateway error.
