Plan the presentation pass: props, NPCs, movement

Replace the flat "future ideas" list with three scheduled sections and concrete,
reviewable checkboxes (41 tasks):

- Better Props: colliders for the generated models (they have none today), a
  placement table with variants, sign/bus-stop/shelter/street-lamp props, a
  close-range detail layer, pipeline audits, and a prop-gallery capture.
- Better NPC Characters: articulated rig, layered outfits and accessories, face
  and hair variety, idle/conversation animation, door-queue staging, reaction
  readability, LOD tiers, and a re-measured NPC budget.
- Better Player Movement: accel/decel split, step-up assist, head bob/FOV and a
  motion-sickness toggle, precision-walk feedback, surface footsteps, gamepad
  support, input remapping, and movement tests.

Kept live 3D replay, extra venues, voice audio, and the image-to-mesh swap in
Future ideas. Memory notes the grounding facts (props have no colliders, rigid
NPC rig, single accel value). Docs-only: no version bump or release.
