What

Expands tests/infrastructure/test_router_cascade.py from 42 unmarked tests (not run by tox -e unit) to 73 fully-marked unit tests.

Changes

Added @pytest.mark.unit to all 12 existing test classes so they are discovered by tox -e unit
Added 8 new test classes covering previously untested paths:
- TestContentTypeDetection — all branches of _detect_content_type() (text, vision, audio, multimodal, list-content)
- TestTransformMessagesForOllama — message transform for base64, URLs, missing files
- TestProviderCapabilityMethods — get_model_with_capability() and model_has_capability()
- TestGetFallbackModel — vision fallback, no-capability fallback, text returns None
- TestCascadeTierFiltering — frontier_required, unknown tier, tier-matched providers
- TestGenerateWithImage — delegates to complete() with images in messages
- TestGetRouterSingleton — get_router() creates instance and returns same instance
- TestIsProviderAvailable — disabled, healthy, open circuit, half-open transition

Test results

tox -e unit — 93 passed (was 20 before this PR)

Add @pytest.mark.unit to all test classes in test_router_cascade.py so
they are picked up by `tox -e unit`. Expand coverage with new test classes
for _detect_content_type, _transform_messages_for_ollama, Provider
capability methods, _get_fallback_model, cascade_tier filtering, the
generate_with_image convenience method, get_router() singleton, and
_is_provider_available circuit-breaker transitions.

Fixes #1138
