BREAKING CHANGE: Application now uses config.yaml instead of .env files
## Changes:
- Remove dotenv dependency from package.json
- Update all services to use ConfigManager for configuration
- Update tests to use fixed credentials instead of env vars
- Delete obsolete config-manager.test.ts (used old .env API)
- Update documentation (README.md, CLAUDE.md) to reflect new config system
## Configuration Architecture:
- ConfigManager: Centralized YAML configuration with Zod validation
- config.yaml location:
- Development: Project root (easy to edit and version control)
- Production: User AppData (persists across updates)
- ERP credentials: Stored in database (dbo_BIPUsers) per user
- Other settings: Stored in config.yaml (database, paths, extraction, etc.)
## Files Modified:
- package.json: Removed dotenv dependency
- cleaner-handler.ts: Use ConfigManager.getDatabaseType()
- run-migration.ts: Read from config.yaml instead of .env
- All integration tests: Use fixed test credentials
- tests/setup.ts: Removed dotenv loading
- README.md, CLAUDE.md: Updated documentation
Migration is complete. Application no longer depends on .env files.
- Add README.md with installation, configuration, and usage guide
- Add docs/USER_GUIDE.md with detailed step-by-step workflows
- Include database setup scripts for MySQL and SQL Server
- Add troubleshooting section with common issues
