Add ADRs 0007–0010 for locomotion, focus ring, radial menu, NPC presentation

- 0007: input layers so WASD/look never fire person-verbs; freeze while modal
- 0008: cone focus + billboarded head ring; no type names in the world
- 0009: doughnut action menu (LMB/Space open, click or A/D then Space, Esc/RMB
  cancel); emergency stays on R
- 0010: keep procedural rigs, add face/hair/neck; no Mixamo this pass
