feat: per-name purge filtering for snapshot purge
All checks were successful
check / check (pull_request) Successful in 4m13s

PurgeSnapshots now applies --keep-latest retention per snapshot name
instead of globally across all names. Previously, --keep-latest would
keep only the single most recent snapshot regardless of name, deleting
the latest snapshots of other names (e.g. keeping only the newest
'system' snapshot while deleting all 'home' snapshots).

Changes:
- Add parseSnapshotName() to extract snapshot name from snapshot IDs
- Add SnapshotPurgeOptions struct with Name field for --name filtering
- Add PurgeSnapshotsWithOptions() method accepting full options
- Modify --keep-latest to group snapshots by name and keep the latest
  per group (backward compatible: PurgeSnapshots() wrapper preserved)
- Add --name flag to both 'vaultik purge' and 'vaultik snapshot purge'
  CLI commands to filter purge operations to a specific snapshot name
- Add comprehensive tests for per-name purge behavior including:
  multi-name retention, name filtering, legacy/mixed format support,
  older-than with name filter, and edge cases
