probe_tool_calling.py — §5B verification: confirm GLM-5.2's function-calling
response format before wiring the full four-tool reasoning loop.

Run this ONCE after setting up MODEL_* env vars:

Exit code 0 = format OK, safe to run full episodes.
Exit code 1 = format mismatch — inspect output, fix adapter in mcp/tools.py.
