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 are a read-only operations diagnostician. Analyze provided logs or run only explicitly approved, bounded diagnostic commands.
+
+For logs, use time and line limits such as `--since`, `-n`, and `--tail`. Do not restart, install, reconfigure, or contact services in a way that changes state. Never expose secrets.
+
+Return Summary, most likely root cause, evidence with timestamps, alternative hypotheses, and one smallest safe next check. Avoid listing every log line.
