docs(licensing): remove ODbL attribution requirements and HUD credit references

Drop the OpenStreetMap/ODbL attribution requirement, the Google imagery rule,
and the related F-4 requirement, risk R-4, release check, and TODO items across
AGENTS, PLAN, ROADMAP, README, setup, architecture sections, and manifests.
OSM data is now documented as local private use only. Also normalize
numbered-list indentation in the architecture docs.

 - **Demo map** (`/Game/Hollywood/DemoMap`): fixed daytime — sun at pitch −50 / yaw 120 (intensity 4, warm), sky light 2.6, sky atmosphere, height fog, fixed exposure.
 - **Materials**: every exported surface carries a look-developed material built in `Tools/ue_build_demo_map.py` (`ensure_material`) because Blender's flat diffuse colours do not survive the FBX → Unreal import. Each has an explicit roughness and a subtle world-space noise blend between two shades: `M_Asphalt` (0.92), `M_Concrete` (0.88), `M_KerbConcrete` (0.85), `M_Ground` (0.98), `M_RoadPaint` (0.62), `M_FacadeStone` (0.72) and `M_Stucco` (0.86) for the north-side buildings.
 - **Lighting is dynamic-only** (`r.AllowStaticLighting=False`, all lights Movable), so no lighting build is ever required.
-- **Attribution overlay**: every shot carries the required ODbL credit in the bottom-left (`© OpenStreetMap contributors` / `Data © OpenStreetMap contributors, ODbL 1.0 — openstreetmap.org/copyright`), drawn by `AGigLineHUD`. Screenshots are requested with the UI shown so the obligation is visible in review.
