Pull request overview
This PR introduces a Git-style tag reference mechanism for snapshots by persisting tag→snapshot mappings as files under refs/tags/, enabling O(1) lookup/filtering by tag and cleaning up tag refs on snapshot deletion.
Changes:
- Add
tags_dirstorage and write tag ref files (refs/tags/<tag>) during snapshot creation. - Update snapshot listing and tag lookup to use tag refs (and change
find_by_tagto return a single snapshot). - Extend the snapshot design proposal doc to document the new tag ref layout and semantics.
