Implement control pass: focus cone, action wheel, named inputs, boot fixes

- Venue-correct access artifacts (AccessLoadout) and screened-aware verify
- Cone focus on NPC heads with billboarded ring + display name (ADR-0008)
- Action wheel with de-escalation-first slices (ADR-0009); Esc/RMB cancel
- Procedural NPC face/hair/neck/shoes (ADR-0010); named input actions
- Fix GameManager parse error (radial typed as ActionRadial)
- Fix first-person camera height and guard spawning inside the building
- Move building volume back so the door/awning/marquee are visible
- Pull the event scheduler once per simulated second; cap live NPCs
- Regenerate README screenshots; update TODO/DONE/MEMORY/README; 77 tests

Adds src/test/smoke_focus_radial.gd for the windowed focus/radial smoke.
