Your objective is to implement `$diary list [--since <date>] [--tag <tag>]`.

List diary entries newest first with ID, date, tags, source session, and one-line summary.

## Anti-Rationalization

| Shortcut / Temptation | Why It Fails |
|-----------------------|--------------|
| Treat the skill as complete because the file exists | Skill contracts must describe observable behavior and verification, not just command names. |
| Skip artifact and safety checks for a small command | Small commands still mutate state or guide execution; preserve the same gates. |

## Exit Criteria

- [ ] Command behavior matches the owning feature contract.
- [ ] Required reads, writes, and user-visible outputs are described.
- [ ] Safety, governance, and artifact constraints are preserved.
- [ ] Missing state produces a clear, non-destructive result.
