feat(simulation): bookmark definition system with bridge protocol (#614)

BookmarkPlugin, BookmarkRegistry, SelectedBookmark resources. Tycoon bookmark
defined; PROTOCOL_VERSION bumped to 22. RequestBookmarkCatalog + ConfirmBookmark
actions wired into process_player_input via BookmarkInputParams SystemParam bundle
(resolves Bevy's 16-system-param limit). build_catalog() accepts optional
CultureResolver for D-128 location-culture mapping. Snapshot delivery at tick-0
via SnapshotBuffer.
