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.

 **Next up:** model the hero façade and block frontage from the reference set, then first-person traversal on the site terrain (tasks in [TODO.md](TODO.md)). **Release gate:** `v0.1.0` is tagged only on the owner's explicit go-ahead once the release checks pass — not automatically when the TODO items close.

 ## 0.1.0 — Local setup and walkable Hollywood block (weeks 1–6)
 
 **Goal:** a walkable exterior demo around 6840 Hollywood Blvd / El Capitan Entertainment Centre, built on verified geography, in one shared coordinate frame, and validated on the Linux workstation. Setup details are in [Docs/setup.md](Docs/setup.md) and pins in [Docs/toolchain.md](Docs/toolchain.md).

 **Asset production:** the scale test and the `ue_metric_v1` export and import presets are established. The hero façade first pass is built and screenshot-approved; the north-side buildings (TCL Chinese Theatre, Madame Tussaud's) are staged. Open: reference collection for the door recess and the night frame, the surrounding block frontage, sidewalks, roads and collision, and materials for all assets.
 
-**Gameplay:** first-person movement, mouse look, pause, and reset are implemented. The walkable demo map is built but has not been checked by hand. Open: the designated crossing, daytime lighting and ambience, and the geographic attribution display.

 **Release checks:** traversal on both sides of the demo, building placement and street scale checked against references, no blocking collision or packaging defects, 60 FPS at 1440p on the documented preset, a fresh checkout that builds with the documented engine installation, a packaged Linux build with documented controls, and then the `v0.1.0` tag and changelog entry. The detailed checks are tracked in [TODO.md](TODO.md).
