Admin d2130e6550 libs: model, mesh_edit, csg, scene, sim, render, xr
Squash of 25 work commits (Sep 1–12):
  237da90  render: the sprite lane hands the screen draw back the way it found it
  895b9a7  particles: an emitter can ride a body's own frame
  914471f  ai-hub: a feed session whose last socket left ends on its idle timeout; skin: parent, skinned centroid and a nodes-only rig for retargets
  3fcccf3  sim: the whole world is implicitly editable, and one seam says where the ground is
  5692fab  sim: the landform world proves itself — walker through the tunnel included
  f4af6df  sim: terrain knows who changed it — a plan layer over player history
  adbb078  render: a water volume can be physics without a picture
  c17480f  render: a non-rigid body may carry its own orientation
  acad401  sim: an agent with no route holds and retries instead of walking into the wall
  22b2bf9  sim + chat: the composed world surface takes a map floor; the chat gets plan tools
  faf8112  web path: the tessellator's lap timer, the trace span and the fusion cycle timer have no clock on the web
  d3472eb  tsdf: the clock-taking XR helpers are native-only — the browser has no depth camera and no Instant
  4946c9e  sim + render: a repaint is not a world edit — colour and glow restyles never rebake the lightmap
  4317f58  sim + render + chat: walk decks as a surface, the filmed body is no obstruction, the brief never asks
  9791279  render: support rigged models and custom materials across viewers
  3ce2792  sim: use deck geometry for collision and sensing
  c8b79ff  Add portable PBR, rig and soft-body authoring support
  108d423  Add transactional polygon modeling and editable asset documents
  38f4d3b  Refine editable modeling and firm yarn character behavior
  08a2637  sim: add entity-owned lights and vehicle headlights
  00d96a7  render: add clustered lights, local shadows and incremental GI
  cf916af  render: import glTF asset extensions and wire clustered GI
  c6d2cca  model: cut transaction memory and raise capacity limits
  41af47a  raytrace: add a CPU probe-ray BVH budget example
  c963d0a  libs: the game sim splits into makepad-scene and makepad-soft-body; render, model, fab and the asset importer retarget
