fix: repair Docker build — TS errors and missing docs in image

- Remove unused `httpx` import from bench.ts (package does not exist)
- Add explicit `IRouter` type on `router` in agent-outputs.ts and bench.ts
  to resolve TS2742 portable-type errors
- Remove `docs` from .dockerignore so Dockerfile.admin can copy it into
  the runner image (DOCS_ROOT=/app/docs is read at runtime by the admin)
