Close gaps: GLM-judge (anthropic registry) + run cancel + deep-link

#2 GLM judge (closes #114): registry NamedProvider gains a `format` field;
build_provider_registry builds an AnthropicProvider for format="anthropic".
GLM's coding/OpenAI endpoint is ToS-throttled for raw SDK, but its Anthropic
endpoint (api.z.ai/api/anthropic) accepts raw API calls (verified x-api-key
-> glm-4.7), so CLAWMATES_JUDGE_MODEL=glm:glm-4.7 routes the door governor /
topology judge through GLM with no runtime-routing. (Kimi-as-judge still needs
a Platform key — coding key is agent-only.)

#3 run-control: POST /api/topology-runs/{id}/cancel (workspace-scoped,
queued/running only); the worker honors it at the step boundary (checks
current_status in the checkpoint callback) and won't clobber a cancel with
`failed`. Frontend Run tab gains a Cancel button and clickable recent runs
that deep-link into a live/replayed stream (SSE replays from checkpoint).

cm-* tests (incl. new cancel test) + clippy + frontend lint/typecheck green.
