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.

README/development-status/Blender AO/Forward+ stale claims were corrected. The v1.0.0 gap register and 0.8/0.9/0.9.5/1.0 roadmap live in `TODO.md`.
 - **Vision judge (v0.7.2):** `tools/openrouter_judge.py` reads `/api/v1/models`, filters image-input models with `response_format`, and ranks by advertised prompt/image/completion prices. `--model auto` (default) uses the cheapest (`z-ai/glm-5.3-flash` on 2026-11-01) with fallbacks; explicit `--model`/`GIG_LINE_JUDGE_MODEL` wins. Auth errors abort, provider/model errors fall through. Full screen judge 13/13 match, 0 diff; A/B judge ~$0.006.
