Implements docs/architecture/world_persistence_impl.md §9's backend task: chunk/room/revision Postgres schema (migration 0005), a Python port of the world.md §3.6 binary chunk codec with golden-file tests, a WorldStore service (world.md §5.1 minus flush_dirty/rebuild_index), the public world-content router (rooms/chunks CRUD, optimistic concurrency, batch writes) and the internal read-only API for dedicated servers, and game_servers.py changes: a per-spawn bearer token, --api-url/--server-token args, and a real "ready"-field wait replacing _await_port, which bound the UDP port before content existed and failed open (no error) past its deadline. create_world now auto-creates the "main" room. Deviations/findings, not silently decided: - chunk_codec.py implements real IEEE-754 float32 packing rather than mirroring a confirmed bug in scripts/chunk_data_decoder.gd's _read_float32/_write_float32, which do a lossy int<->float cast instead of a bit reinterpretation (verified against Godot 4.6.2 headless) and will corrupt any non-integer position/rotation/scale/bounds value. Not fixed here (client-side, out of scope); flagged for the client task. - world_persistence_impl.md references a world's monotonic content_revision (§6/§7.2/§8.1) but never defines where it's stored. Resolved as MAX(id) over the append-only world_chunk_revisions table, scoped to world_id, rather than adding an undocumented column. - No existing Godot-side golden fixture/test vectors were found to reuse, so tests/fixtures/chunks/*.bin are authored fresh from this implementation (see generate_fixtures.py). Verification: 132/132 backend pytest tests pass against a real ephemeral Postgres (both reusing an already-running instance and cold via conftest.py's own docker-compose bootstrap), including migration upgrade/downgrade/upgrade, codec round-trip + validation-error tests, and full HTTP round trips for PUT/GET/batch/delete/revisions/rollback and the internal API's token auth.
