Move Playwright from dev to production dependencies and implement robust browser
management for company deployment environment:
- Move playwright and playwright-core to dependencies
- Set PLAYWRIGHT_BROWSERS_PATH to user data directory before imports
- Add startup validation for Chromium browser with friendly error dialog
- Update build scripts to skip browser download during build process
- Configure electron-builder to unpack Playwright for native module access
- Add deployment documentation for browser setup in restricted environments
This allows manual browser installation in company environments where direct
downloads are blocked during build.
