Hongming Wang 7c3aeb5a14 ci: install pyyaml so the YAML-loading test path is exercised ... Without pyyaml in CI, adapter._load_providers' broad except-Exception swallows the ImportError and silently falls back to _BUILTIN_PROVIDERS. Tests then assert 7 providers but get 2; setup() can't route any third-party model. Locally pyyaml is system-installed so the issue went unnoticed. Same failure mode as the 2026-04-30 incident (CI green, prod broken) — pinning the dep here closes that gap.
