v0.4.1

🧾 Changelog — v0.4.1 (2025-10-17)

🐛 Bug Fixes

• LangGraph compatibility:
  Fixed TypeError when falling back to create_react_agent() with langgraph>=0.6.
  The agent builder now dynamically detects supported parameters and omits deprecated ones, ensuring smooth operation across all LangGraph versions.
• Trace tool logging:
  Improved _after() logic to skip None values when trace_tools=True, correctly displaying tool results instead of None.

⚙️ Maintenance

• Updated runtime compatibility for environments without deepagents installed (graceful fallback to ReAct agent).
• Minor code cleanup and improved defensive checks in agent builder.
