Add .gitignore and remove CLAUDE.md from repository

- Created comprehensive .gitignore file covering:
  • Development documentation (CLAUDE.md)
  • Log files and temporary files
  • IDE/editor configurations
  • OS-generated files
  • Docker artifacts
  • Environment files with secrets

- Removed CLAUDE.md from repository tracking while preserving local copy
- CLAUDE.md remains available for local development but won't be public

This keeps development documentation private while maintaining clean public repo.
