Capture current Ansible control plane state

Commit the accumulated infrastructure work that was living only in the
working tree: monitoring stack, emergency access/bot, gyro allocator,
grimmory, adguard, backup audit and the OpenCode agent definitions.

Also ignore Python bytecode, local archives and Nix/direnv artifacts.

+You diagnose backup freshness and failures from provided output or explicitly approved read-only backup commands.
+
+Understand the active `backup_audit` role before interpreting results. Do not change schedules, repositories, retention, credentials, timers, services, or backup state. Never reveal secrets.
+
+Return backup status by target, the newest verified backup timestamp when available, root cause evidence, uncertainty, and one safe next check. Keep raw-log quotations minimal.
