Apply the PR #175 comprehensive reliability patch on e4ea3be:

- Resume exact-byte immutable candidates; never rebuild from a newer working DB
- Persist and recheck referenced-asset fingerprints before manifest CAS
- Publish media/stems/artwork under content-addressed paths
- Scope generation DB objects by operation hash to avoid concurrent collisions
- Keep GC from deleting other writers' in-flight staging data
- Repair restart digests only from Clean with no active operation

Also allow directory bulk-upload helpers that the CAS path no longer calls so
clippy -D warnings stays clean.
