fix: Use local .git/ai-agents-temp/ for Claude CLI file permissions

Changed temp file location from /tmp to .git/ai-agents-temp/ to resolve
Claude CLI permission errors when reading discussion content.

Problem:
- agents.py created temp files in /tmp/tmp*.md
- Asked Claude CLI to read these files
- Claude CLI couldn't access /tmp without explicit permission grant
- Error: "I don't have permission to read that file"
- Fell back to basic pattern matching (degraded functionality)

Solution:
- Create temp files in .git/ai-agents-temp/ directory
- Claude CLI has permission to read files in the project directory
- Use PID for unique filenames to avoid conflicts
- Cleanup still handled by finally block

Benefits:
- No user configuration needed
- Claude CLI can now read discussion files
- AI agents work properly for structured extraction
- Temp files automatically gitignored (.git/ directory)
- Easy debugging (files visible in project)

The finally block at line 154-158 still cleans up temp files after use.
