feat(WARDEN-WP-0020): T3 — guarded executor (worker now acts, not just plans)
HubClient gains writes (mark_read, send_reply, add_progress). execute_plan/execute_plans run the safe, allowlisted actions autonomously: route_answer (reply with the computed answer + auto mark-read), reply (LLM-drafted body), progress_note, mark_read. Escalated plans and non-auto-executable kinds are left for a human; every action is metadata-only (no secret value read/sent/logged). Deliberate guardrail: propose_catalog_diff and any code/routing change is NOT auto-executed even under full-auto — a bad catalog commit could misroute credentials, so it goes to human review (recoverability over convenience). AUTO_EXECUTABLE is the messaging/hub tier only. `warden worker run --execute` runs the executor (dry-run still default). 7 executor tests (reply+mark, with/without body, escalated skip, catalog-diff-left-for-human, progress, failure-without-crash); 243 pass, lint clean. First live --execute shakedown is the operator's (staged rollout); T4 schedules it. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
