Add responses sub-patches to the six o-series quirks entries (temperature
and top_p removal; reasoning.effort high for the -high aliases) and
regenerate models.yaml from live models.dev/openrouter data, picking up
expected upstream price and model drift.
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.
