## Summary
`PurgeSnapshots` now applies `--keep-latest` retention per snapshot name instead of globally across all names.
### Problem
Previously, `--keep-latest` would keep only the single most recent snapshot across ALL snapshot names. For example, with snapshots:
- `system_2024-01-15`
- `home_2024-01-14`
- `system_2024-01-13`
`--keep-latest` would keep only `system_2024-01-15` and delete the latest `home` snapshot too.
### Solution
1. **Per-name retention**: `--keep-latest` now groups snapshots by name and keeps the latest of each group. In the example above, both `system_2024-01-15` and `home_2024-01-14` would be kept.
2. **`--name` flag**: New flag to filter purge operations to a specific snapshot name. `--name home --keep-latest` only purges `home` snapshots, leaving all `system` snapshots untouched.
### Changes
- `internal/vaultik/helpers.go`: Add `parseSnapshotName()` to extract the snapshot name from a snapshot ID (`hostname_name_timestamp` format)
- `internal/vaultik/snapshot.go`: Add `SnapshotPurgeOptions` struct with `Name` field, add `PurgeSnapshotsWithOptions()` method, modify `--keep-latest` logic to group by name
- `internal/cli/purge.go` and `internal/cli/snapshot.go`: Add `--name` flag to both purge CLI surfaces
- `README.md`: Update CLI documentation
### Tests
- `helpers_test.go`: Unit tests for `parseSnapshotName()` and `parseSnapshotTimestamp()`
- `purge_per_name_test.go`: Integration tests covering:
- Per-name retention with multiple names
- Single-name retention
- `--name` filter with `--keep-latest`
- `--name` filter with `--older-than`
- No-match name filter (all snapshots retained)
- Legacy snapshots without name component
- Mixed named and legacy snapshots
- Three different snapshot names
### Backward Compatibility
The existing `PurgeSnapshots(keepLatest, olderThan, force)` signature is preserved as a wrapper around the new `PurgeSnapshotsWithOptions()`. The `--prune` flag in `snapshot create` continues to work unchanged.
`docker build .` passes (lint, fmt-check, all tests).
