Pull request overview

Syncs this repository’s GitHub Actions workflow templates and LLM tooling pins to match the upstream stranske/Workflows template set, keeping automation and dependency installs reproducible.

Changes:

• Updated pinned GitHub Action SHAs across multiple workflows (e.g., create-github-app-token, setup-node, download-artifact, cache, claude-code-action).
• Adjusted tools/requirements-llm.txt LangChain-family strict pins used by workflow automation.
• Simplified tools/langchain_client.py by inlining the optional langchain_anthropic import handling.
