"""Demo: how to use DebugLogger in real scripts.

Run this from the cq2_sdk directory:

    uv run python scripts/demo_debug_log.py

It exercises 4 patterns:
  1. basic context-manager + step()
  2. HTTP request/response correlation
  3. error event from a caught exception
  4. auto-error on context-manager exit when an exception escapes

Output: a new .jsonl file in D:\\传奇\\debug_logs\\.

After running, try:

    cat "D:/传奇/debug_logs/session_*.jsonl" | head
    # or in OpenCode: ask it to read the newest session_*.jsonl
