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.
**Core Implementation (src/main/services/erp/cleaner.ts):**
- CleanerService class with dry-run mode support
- Material deletion logic with safety constraints:
- Row numbers 7000-7999 are protected
- Materials with pending quantity are skipped
- Materials not in delete list are ignored
- Order processing with nested iframe navigation
- Progress callback support for UI integration
**Types (src/main/types/cleaner.types.ts):**
- CleanerInput: order numbers, material codes, dry-run flag
- CleanerResult: processing statistics and details
- OrderCleanDetail: per-order breakdown
**Tests:**
- Unit tests for shouldDeleteMaterial logic
- Integration tests for order processing
- Dry-run mode validation
- Navigation tests
