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.
