refactor(store): extract snapshot layer into muse.core.snapshots

Move SnapshotRecord, SnapshotDict, write_snapshot, read_snapshot, read_snapshot_result, the typed result variants (SnapshotReadOk/NotFound/Corrupt), snapshot_read_is_ok/corrupt, snapshot_path, _verify_snapshot_id, get_commit_snapshot_manifest, and get_head_snapshot_manifest out of muse/core/store.py into a new muse/core/snapshots.py module.

All symbols remain importable from muse.core.store via re-exports so no callers need updating. _SNAPSHOT_SCHEMA_VERSION is also re-exported to preserve existing test imports.
