mail-negotiator: classify merchant replies, draft gated, audited sends

- IMAP poll (UNSEEN, stdlib imaplib) -> parse (bare address via email.utils)
- threading: In-Reply-To -> outbound sent-draft message-id -> proposal
- classify: deterministic rules; optional LLM behind provider interface;
  below-threshold confidence -> needs_review (never guessed)
- unthreadable approvals flagged needs_review (suspicious by definition)
- merchant_status recorded on proposal detail; proposal lifecycle untouched
- reply drafts generated from templates (drafted), NEVER auto-sent
- SMTP sends only draft_status=approved (human approve_draft, audited);
  sent drafts store their Message-ID for future threading
- idempotent on Message-ID; DaemonRun wrapper for monitor

tests: 9 new (classification rules, threshold->review, threading, idempotence,
blocked send without approval, approve->send->audit chain, double approve)
— 29 total passing

+"""executor — executes APPROVED proposals through registered action plugins.
+
+Guarantees
+----------
+- Only ``approved`` proposals execute (``AUTONOMOUS_MODE=false`` default).
+- With ``AUTONOMOUS_MODE=true`` the executor gains exactly one capability:
+  bounded auto-approval of ``proposed`` items whose ``kind`` is in
+  ``CAYCE_OPS_AUTONOMOUS_KINDS``, capped by ``CAYCE_OPS_AUTONOMOUS_DAILY_CAP``,
+  recorded with actor ``auto:policy`` (DECISIONS D5).
+- Every transition writes an ``audit_log`` row: who approved, what ran,
+  plugin output, success/failure.
+- Unknown proposal kinds fall back to the ``log_action`` plugin (never a
+  network side effect). See DECISIONS D9.
