Compact the plan and synchronize project documentation

- reduce PLAN.md from a 674-line implementation log to a 187-line product/design
  plan; keep escalation, venues, NPC/systems, controls, presentation and constraints
- refresh README for implemented venues, Blender/v2 assets, the custom test runner,
  Web target, current release state and the screenshot smoke
- update architecture for 0.6.0, the runtime art loader, Gitea CI/build/publish,
  Web deployment, six release artifacts and visual regression
- remove stale uncommitted/active-pass claims from MEMORY and point it at the
  current NPC follow-ups; move the completed documentation task to DONE

       instead of 50°, so the facade shades the near sidewalk and props cast long shadows. Ground

+- [x] Make the flashlight read in the dark: narrowed the cone (30° → 14°, range 20 m, forward
+      aim) so it lights the door instead of washing the facade, raised the spot/glow at night, and
+      staged the two night captures in LATE instead of dusk (`capture_screenshots.gd`). The judge
+      moved `06-night-flashlight` from **diff (1.00) to review (0.10)**. A visible beam *shaft*
+      is not possible on GL Compatibility (no volumetrics): an additive cone was tried and
+      rejected because a first-person view inside it renders as a filled disc, so it is tracked
+      as a follow-up for a Forward+ desktop preset.

       The Blender library has the budgets for one more detail pass (fingers, sleeves, faces).
 - [x] Re-check the `screen_designs.py judge` default model (`google/gemini-2.5-flash-lite`): on
       2026-11-01 it returned 7 match / 4 review / 0 diff without a provider error; `--model`
       override is documented in `README.md`.
+- [ ] Add a true flashlight light shaft (volumetric spot) once a desktop Forward+ preset exists;
+      the Compatibility fallback stays the tight pool. See `DONE.md` → environment renderer note.
 - [ ] Add the two venue stages to the committed gallery (they are capture-only today) and give
       the Joke Shop and studio their own geometry so their concept comparisons are geometric,
       not just lighting.
