feat(curator): per-run reports — run.json + REPORT.md under logs/curator/ (#17307)

Every curator pass now emits a dated report directory under
`~/.hermes/logs/curator/{YYYYMMDD-HHMMSS}/` with two files:

- `run.json` — machine-readable full record (before/after snapshot,
  state transitions, all tool calls, model/provider, timing, full LLM
  final response untruncated, error if any)
- `REPORT.md` — human-readable markdown: model + duration header,
  auto-transition counts, LLM consolidation stats, archived-this-run
  list, new-skills-this-run list, state transitions, the full LLM
  final summary, and a recovery footer pointing at the archive + the
  `hermes curator restore` command

Reports live under `logs/curator/`, not inside `skills/` — they're
operational telemetry, not user-authored skill data, and belong
alongside `agent.log` / `gateway.log`.

Internals:
- `_run_llm_review()` now returns a dict (final, summary, model,
  provider, tool_calls, error) instead of a bare truncated string so
  the reporter has full fidelity
- Report writer is fully best-effort — any failure logs at DEBUG and
  never breaks the curator itself. Same-second rerun gets a numeric
  suffix so reports can't clobber each other
- Report path stamped into `.curator_state` as `last_report_path`
- `hermes curator status` surfaces a "last report:" line so users
  can immediately open the latest run

Tests (all green):
- 7 new tests in tests/agent/test_curator_reports.py covering: report
  location (logs not skills), both files written, run.json shape and
  diff accuracy, markdown structure, error path still writes, state
  transitions captured, same-second runs get unique dirs
- Existing test_run_review_synchronous_invokes_llm_stub updated to
  stub the new dict-returning _run_llm_review signature

Live E2E: ran a synchronous pass against a 1-skill test collection
with a stubbed LLM; report written correctly, state stamped with
last_report_path, markdown human-readable, run.json machine-parseable.
