- Change cache location from .pi-project-map/cache/ to .cache/pi-project-map/
- Cache is now hidden by default (dot directory)
- Add .cache/ to .gitignore
- Remove committed .pi-project-map/cache/ from repo
- Use processFiles from llm-batch.ts in generateDirectoryMap
- Process files with 4 concurrent LLM calls + 100ms batch delays
- Reduces init time from O(n) sequential to O(n/4) parallel
- Prevents Pi tool timeout on projects with many files
