Black-box scenarios against a built binary with dry_run configs: hook
cadence + env scoping, runtime inertness of failing hooks, --info firing
zero agent.* events, --install-builtins hooks install/force/cold-start
semantics, and end-to-end firing of the installed log-events.sh via the
documented relative-path wiring.
Add a hidden --generate-models flag that rebuilds models.yaml from
models.dev and OpenRouter merged with the hand-owned quirks overlay,
regenerate the committed catalog with it (393 -> 1090 models), and
retire the Python updater. GitHub becomes fully quirks-owned since
upstream only tracks Copilot ids, legacy ids upstream dropped are
preserved as hand-owned quirks entries, and non-chat model families
(image/tts/audio/realtime) are excluded from generation.
