NS-24: Eliminate idle jitter and movement QA bumps (Godot client)
Physics: Jolt 3D; physics_interpolation off; 120 TPS. CharacterBody3D idle
path uses dual floor_max_angle, rim/straddle and ridged-contact handling,
rim settle and random-floor-bump lip/wall escape, floor_block_on_wall,
NavigationAgent3D avoidance off, per-node interp off. No global_transform in
_process (avoid render/physics ghosting).
QA geometry: random_floor_bumps.gd (load from main.gd); each bump on its own
StaticBody3D under NavigationRegion3D; random_floor_bump_collision_constants.gd
for collider fudge and RANDOM_FLOOR_BUMP_MESH_GROUP.
Scene: player safe_margin and mesh Y lift; MoveRejectPedestal / MoveRejectFarPad
renamed from NS19*; Mat_player_capsule without polygon_offset (per follow-up).
Docs: NS-24 plan + resolution, client/README manual steps, code review
2026-04-05-NS-24.md; server/README bump height note. Code/scene identifiers
avoid ticket-based ns19_* naming.
