• Update pinned GitHub Action SHAs (notably actions/setup-node) and bump the Claude Code Review action SHA.
• Refresh consumer-facing docs (CLAUDE.md, new AGENTS.md, and a small WORKFLOW_USER_GUIDE.md section update).

scripts/langchain/semantic_matcher.py:33

• EmbeddingClientInfo.client is now typed as object, but this module later calls resolved.client.embed_documents(...) (and the adapter also exposes embed_query). Using object makes the type hint inaccurate and removes the interface contract for callers passing a custom client. Consider restoring a small Protocol (or another structural type) that declares the required methods, and use that for client so the expected API remains documented and checkable.

@dataclass
class EmbeddingClientInfo:
    client: object
    provider: str
    model: str
    is_fallback: bool
