geo: add block extract, boundary verification, and the carried-over reference set

Browse Source 
Inventory the sibling security-game project and copy only the evidence: nine
licensed photos with their sidecar provenance into Art/reference/hollywood/,
now LFS-tracked. Add the block-wide OSM extract with a manifest, resolve the
demo bounds (Orange Dr -118.341434 .. Highland Ave -118.338718, 279 m) and the
south/north building sets, and add Geo/scripts/block_report.py to reproduce it.

The sibling docs place the El Capitan Theatre west of 6840; OSM geometry and
the house numbering put it east. Recorded with the two unresolved measurement
conflicts rather than averaged.

## Reference photography (development only, not shipped)
Available in the sibling project `…/06-games/security-game/docs/screens/refs/hollywood/`, with per-file provenance in its `SIDECAR.md`. Nothing here is committed to this repository yet; the licences below are recorded so the set can be brought over with correct attribution.
Committed in `Art/reference/hollywood/` (Git LFS). Copied 2026-11-06 from `…/06-games/security-game/docs/screens/refs/hollywood/`, which holds the per-file provenance in `SIDECAR.md` — carried over verbatim with the images. These are development evidence and are not built into the game.
