Consolidate architecture docs and add the v1.0.0 roadmap

Make architecture the canonical system/data-flow source, add explicit
documentation ownership and consolidation rules, and mark the old graphics plan
historical. Fix stale README/status/Blender/release claims. Add a full gap
register and milestone roadmap from v0.8 through v1.0.0, including onboarding,
content depth, accessibility/localization, performance, release/legal blockers
and non-blocking future ideas.

 ## Development Status
 
-v0.7.0 shipped distinct venue geometry: the Joke Shop alley and TV Studio
-entrance no longer share the Hollywood layout. It builds on v0.6.1's fitted NPC
-gear and v0.6.0's Blender asset library, baked AO and environment lift. See
-[`docs/development-status.md`](docs/development-status.md) for the full
-implemented list and [`TODO.md`](TODO.md) for what's next. Manual verification
-uses the [`docs/smoke-checklist.md`](docs/smoke-checklist.md).
+v0.7.2 ships the cost-aware OpenRouter judge and the optional Desktop HQ build.
+The three venues now have distinct geometry, fitted NPC gear, the Blender asset
+library and the post-v0.6.0 realism pass. See
