Rename Step Line to Gig Line

Update the game name in project.godot, export presets, UI/marquee/title strings, packaging (AppImage/NSIS/desktop/appdata), tools, docs, and the generated prop GLBs. Packaging assets and README screenshots are regenerated. Headless suite 209/209 and Python tooling tests pass.

 - Prop atlas (v0.3.1): `tools/model_pipeline.py` packs each prop's palette into one power-of-two colour atlas plus a metallic/roughness atlas and emits a single material with per-vertex UVs, so a prop is one draw material rather than one per part; `audit` enforces the contract
 - Generated prop models (v0.3.0 work): `tools/model_pipeline.py` builds bollards, benches, bins, planters, newspaper boxes and a hydrant as `.glb` props with per-part materials, loaded by `WorldBuilder` with a procedural fallback; the optional AI concept step (`model_pipeline.py concept`) supplies per-prop colour palettes
 - NPC base model (v0.6.0 assets): `tools/npc_pipeline.py` builds a skinned, UV-mapped base character (`assets/models/generated/npc_base.glb`) with per-slot albedo/normal/ORM maps and an armature matching the procedural rig's node names; AI fabric albedos (shirt/trousers) and a derived `palette.json` are layered in.

 - Aim-free selection pass (v0.3.0 work, [ADR-0011](docs/adr/0011-aim-free-selection-and-precision-walk.md)): the focus cone ranks candidates by angle then distance, `Tab` and the mouse wheel cycle nearby people nearest-first and pin the selection, right click clears focus with a short re-acquire grace, the HUD reports how many people are in the ring, and holding `Shift` walks at half speed for close work
 
 Not yet implemented: wiring the authored NPC base model into the live game (`NpcAvatar._load_model`, see [`docs/plan-graphics-v0.6.md`](docs/plan-graphics-v0.6.md) — the procedural rig still renders for now), live 3D body-camera replay, editor-based GUT integration, and crowd performance profiling/LOD (see `TODO.md`).
