feat: Add database setup guide and local configuration files
- Added DATABASE_SETUP.md with comprehensive guide for PostgreSQL and Redis installation on Windows - Created .claude/settings.local.json with permission settings for pytest and database fix scripts - Updated .gitignore to exclude .env.backup file - Included database connection test utilities in lyra/database_setup.py - Added environment variable configuration examples for local development
