feat: route on the input modalities a request requires - #42

Conversation
A request declares the modalities it needs and a model whose card does not list them all is never a candidate, as a deterministic capability restriction applied before scoring. The committed catalog stays text-only. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

What
Adds the last routing feature the spec lists that was missing (§7.2, "Required modality").
How
routing.modalitiesdeclares the inputs a request needs (text,image,audio; defaulttext).modalities(defaulttext), which flows through the catalog to the router and into the MLflow record.422.Tests
Three tests in
tests/unit/test_routing_features.py: a higher-scoring text-only model is skipped for an image request; a modality no model accepts is refused and an empty requirement is invalid; the card's modalities reach the router.Local: ruff and mypy clean, 479 tests pass, Playwright 9/9.
Limits
This is a routing restriction only. Every model in the committed catalog is text-only and message content is still text, so the gateway does not yet accept image or audio content itself.
