- Adopt origin's SnapshotPurgeOptions naming and PurgeSnapshotsWithOptions
method, but extend with Names []string (repeatable --snapshot flag) and
Quiet bool for use by --prune.
- Adopt origin's parseSnapshotName helper.
- Fold the duplicate post-backup prune block into one runPostBackupPrune
call that filters retention to the snapshot names just backed up.
- Keep the shallow-verify timestamp parsing fix and the dead deep-verify
branch removal; use origin's printVerifyHeader/verifyManifestBlobsExist
helper extraction.
- Drop top-level vaultik purge and verify (duplicates of snapshot purge
and snapshot verify).
- Drop the resurrected daemon block from info.go (config fields no
longer exist).
- Combine Makefile targets: gofmt -l for fmt-check, -race for tests,
release/release-snapshot/docker/hooks/deps/test-coverage all included.
