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.
