feat(types): tolerant no-vision model matching (Ollama ":size" tags)

Add modelInList(list, modelId): matches the full id OR the family before a ":size"
tag, so a "gpt-oss" classification covers "gpt-oss:120b"/"gpt-oss:20b". Colon-less
ids (grok-build-0.1) still match exactly. Used by the vision-sidecar gate and the
web-search describeImages flag (both consume provider.noVisionModels).
