feat(ansible): Canonical IaC playbook for fleet management

Implements the Ansible Infrastructure as Code story from KT 2026-04-08.

One canonical Ansible playbook defines:
- Deadman switch (snapshot good config on health, rollback+restart on death)
- Golden state config deployment (Anthropic BANNED, Kimi→Gemini→Ollama)
- Cron schedule (source-controlled, no manual crontab edits)
- Agent startup sequence (pull→validate→start→verify)
- request_log telemetry table (every inference call logged)
- Thin config pattern (immutable local pointer to upstream)
- Gitea webhook handler (deploy on merge)
- Config validator (rejects banned providers)

Fleet inventory: Timmy (Mac), Allegro (VPS), Bezalel (VPS), Ezra (VPS)

Roles: wizard_base, golden_state, deadman_switch, request_log, cron_manager

Addresses: timmy-config #442, #443, #444, #445, #446
