* feat: move github workflows to gh cli
Use LangSmith proxy auth to support gh-driven GitHub workflows while removing custom GitHub wrapper tools.
* docker ignore + snapshot and docker image updates
* updated image and instructions
* removing open_pr if needed after agent call
* fix: warn against using http_request for GitHub PR creation
- Root cause: http_request tool description and system prompt lacked explicit guidance not to use it for GitHub PR operations, causing the agent to fall back to it and receive 401 Unauthorized responses
- Change: added clear warnings to both the http_request docstring and the TOOL_USAGE_SECTION in prompt.py directing agents to use commit_and_open_pr instead
- Verified: docstring and prompt changes are minimal and scoped
* fix: clarify http_request PR guidance
