feat(curator): show rename map in user-visible summary (#22910)

* feat(curator): show rename map (where skills went) in user-visible summary

The full data has always been on disk in REPORT.md, but the user-visible
curator summary (gateway 💾 line, CLI session-start panel,
`hermes curator status`) was counts-only — "consolidated 4 into 2
umbrellas" with no names. Users only discovered renames when something
they expected was gone.

New `_build_rename_summary()` formats the rename map and appends it to
`final_summary`:

    auto: 1 marked stale; llm: consolidated 2 into 1, pruned 1
    archived 3 skill(s):
      • docx-extraction → document-tools
      • pdf-extraction → document-tools
      • old-stale-thing — pruned (stale)
    full report: hermes curator status

Empty on no-op ticks (no archives), so most ticks add zero log noise.
Cap of 10 entries keeps agent.log readable when a 50-skill
consolidation lands; the full list is always in REPORT.md.

`hermes curator status` indents continuation lines so the multi-line
summary reads as one logical field.

5 new tests in tests/agent/test_curator_classification.py covering
empty / consolidation / pruning / cap / mixed cases.

* feat(curator): show recent run summary once on `hermes update`

The rename map is now visible from where users actually look — the
update flow they explicitly run, instead of just the live gateway log
or transient CLI session-start panel.

Behavior:
- After `hermes update`, if the most recent curator run produced a
  rename map (multi-line summary) that the user hasn't seen yet, print
  it once with a 'last run Xh ago' header and a one-time-message
  footer.
- Stamp `last_run_summary_shown_at = last_run_at` after printing so
  subsequent `hermes update` invocations are silent until a newer
  curator run lands.
- Silent on no-op runs (single-line summary like 'auto: no changes;
  llm: no change'). Still stamps shown so we don't reconsider on
  every update.
- Silent when the curator has never run (the existing first-run
  notice handles that case).

Output:

    ℹ Skill curator — last run 4h ago
      auto: 1 marked stale; llm: consolidated 2 into 1, pruned 1
      archived 3 skill(s):
        • docx-extraction → document-tools
        • pdf-extraction → document-tools
        • old-stale-thing — pruned (stale)
      full report: hermes curator status
      (This message shows once per curator run. View anytime: hermes curator status)

State migration:
- `_default_state()` gains `last_run_summary_shown_at: None`. Existing
  state files lack the field; `.get()` returns None; the comparison
  treats any prior run as 'not yet shown' and prints once on next
  update. Self-healing.

Wiring:
- Both `hermes update` paths in main.py call the new
  `_print_curator_recent_run_notice()` right after the existing
  first-run notice. Best-effort try/except so a state-load bug
  never breaks the update flow.

6 tests in tests/hermes_cli/test_curator_recent_run_notice.py:
no-run / single-line / multi-line / show-once / new-run-resets /
time-formatter buckets.
