[BUG] Context bleeding between concurrent Claude Code sessions

• Issue: Claude Code mixed commit messages between two simultaneous sessions running in different terminals
• Expected: Each Claude Code session should maintain isolated context
• Actual: Session A (VirtualTrade/MariaDB work) pulled commit message content from Session B (Docker port conflicts work)
• Impact: Incorrect commit messages, potential context confusion
• Environment: Multiple terminal sessions running Claude Code concurrently

Claude Code version: v1.0.27
Model: claude-sonnet-4-20250514

Steps to Reproduce:

1. Open Claude Code session in Terminal A
2. Open Claude Code session in Terminal B
3. Work on different topics in each session
4. Notice context bleeding between sessions

Evidence:
The commit message incorrectly referenced "Fix Docker port conflicts with dynamic port assignment and cleanup obsolete files" when the actual change was only MariaDB binlog cache configuration.
