Character and movement pass

NPC characters
- Articulated rig (hips/knees, shoulders/elbows/hands) replaces rigid capsules;
  the walk cycle bends knees and elbows and flees with a longer stride.
- Layered outfits (jacket/vest/coat/dress), extended accessories and hand items
  (bag, umbrella, phone, camera, clipboard, cup), face details and five hair
  silhouettes, all deterministic per profile seed.
- Idle behaviour layers (phone, clipboard, crossed arms, look-around), breathing
  and weight shift; escalation raises hands or points, and noticed NPCs turn
  toward the guard.
- Reaction symbols above the head (!!, ?!, !, ?), door-queue offsets assigned by
  GameManager, three LOD tiers with hysteresis and a billboard impostor.
- smoke_npc_budget.gd: 16 avatars = 534 meshes, ~6.9 ms average (50 ms budget).

Player movement
- Separate accel/decel, step-up assist for kerbs and the entrance steps, and a
  forward-axis fix: W was inverted (get_axis(forward, back) is negative).
- Head bob, landing dip and precision-walk FOV, gated by persisted head-bob and
  invert-Y settings; precision chip and tick; surface-aware footsteps and a
  landing cue forwarded to AudioFeedback.
- Gamepad support (sticks, deadzone, face buttons, bumpers), a control legend
  that follows the active device, and named actions for the remaining keys.
- Key/button remapping in Settings, persisted as input_bindings and applied by
  InputBindings (mouse and gamepad axes are never removed).
- smoke_movement.gd (windowed): climbs the steps, checks precision speed, chip,
  footsteps and landing; new 11-precision-walk capture and catalogue entry.

Verification: headless 208/208, Python tooling 56/56, all 11 smokes pass,
compare 11 good / 0 bad, movement judge match. Version 0.5.0. Only optional
Future ideas remain in TODO.
