Fixes #1268

What

Adds point-in-time snapshot support to the Mnemosyne archive.

Archive methods

  • snapshot_create(label) — serializes current archive to a timestamped JSON file in ~/.hermes/mnemosyne/snapshots/
  • snapshot_list() — lists all snapshots newest-first with metadata
  • snapshot_restore(snapshot_id) — replaces live archive with snapshot state (persists to disk)
  • snapshot_diff(snapshot_id) — shows added/removed/modified entries vs current state

CLI

mnemosyne snapshot create [--label LABEL]
mnemosyne snapshot list
mnemosyne snapshot restore <snapshot_id>
mnemosyne snapshot diff <snapshot_id>

Tests

17 new tests in test_snapshots.py covering all operations, edge cases (empty archive, missing snapshot IDs, persistence after reload, modified entry detection).
