Merge main at cultlib-unity-v2.0.0 (42dce361) into C2a: one owner per collision

Browse source 
Identity: C2a's StoredSchemaId/StoredVersion owns; main's PersistedSchemaId, PersistedIdentity and both MarkWritten are deleted. Stamp rule: ReadStore judges the stamp before the body. Flush over damage refuses (merge-r1-precedence). Mesh single-file writes route through SingleFileMessagePackBackingStore. TS: store-file.ts commits, C2a's header handling kept. Rust: C2a's readable_store_format in front of the grown decoder. Build not yet verified at this commit.
