Squashed from work; the fine-grained history is under tag archive/work-2026-08-29:
- mp* wave: mpwm window manager + the mp app family, WM API, theme bridge, PDF engine fix
- mpwm polish wave: terminal key focus, focus-history close order, pop-back-to-origin, occupied-workspace cycling, demo
- work: land the sources the last commits reference
- route: the assistant icon the committed UI references
- fast_inflate: the benches name their dev-deps
- gif/weezl: drop the vendored benches nobody can run
- weezl: the decode tests generate their own LZW fixture
Drop the archived old/ tree, root AI notes, splashgame.md (Arcade lives
in the private sandbox), widgets-dll leftovers, and LAN/oracle helper
scripts. Move download_*.sh into tools/, and move sim/math out of
libs/game/ so the public repo no longer has a game/ directory.
Also quiet first-party compile noise and skip asset-ui tests that need
sandbox kits or uncommitted fixtures.
hotload_ui and xr pulled a dylib widgets wrapper that made
`cargo build --workspace` fail. XR now uses normal widgets.
The vendored weezl async test needed tokio, which we do not ship.
