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.

@@ -46,4 +46,4 @@ Implemented so far:
 - Venue geometry (v0.7.0): the Joke Shop now builds as a narrow brick alley with a warm wall lantern, shutters, dumpster/AC clutter and no skyline; the TV Studio builds a stone facade, bulb canopy, glossy black car and barrier line. `WorldBuilder.VENUE_SPECS` drives facade/street/nav dimensions, and `GameManager` rebuilds only the world container when the venue changes.
 - Gear fit (post-v0.6.0): Blender gear is measured against the avatar head/skirt silhouette and the checks run in both the Python tooling and the headless suite. Sunglasses, the shoulder bag and the firefighter helmet were fitted to the new faces; the Influencer portrait and gallery were recaptured with a before/after report.
 
-Not yet implemented: a desktop-only Forward+ preset (the renderer stays GL Compatibility for Web parity), live 3D body-camera replay, editor-based GUT integration, and crowd performance profiling/LOD (see [`TODO.md`](../TODO.md)).
+Current gaps for v1.0.0: onboarding/campaign progression, deeper authored content and NPC dialogue, mid-shift save/resume and replay, localization/accessibility expansion, voice/audio production, wider performance profiling, signed/notarized release packaging, and a unified Godot baseline. The full gap analysis and milestone plan live in [`TODO.md`](../TODO.md); the current architecture and documentation ownership map are in [`docs/architecture.md`](architecture.md).
