NEW FEATURES:
1. Plugin Dependency Declaration (BasePlugin):
- Added 'dependencies' class attribute
- Format: {'pip': ['package1', 'package2'], 'optional': {...}}
- Plugins can declare required pip packages
2. Plugin Dependency Manager (core/plugin_dependency_manager.py):
- Checks if declared dependencies are installed
- Installs missing packages via pip
- Tracks installation status
- Shows progress dialog during installation
3. Settings Dialog Integration:
- When enabling a plugin with dependencies, shows dialog
- Lists missing dependencies
- Asks user if they want to install
- Shows progress bar during installation
- Handles installation failures gracefully
4. Example: Game Reader Test plugin:
- Declares dependencies: pillow, numpy
- Optional: easyocr, pytesseract, paddleocr
- When enabled, prompts to install if missing
WORKFLOW:
1. User enables a plugin in Settings → Plugins
2. System checks if plugin has dependencies
3. If dependencies missing, shows dialog
4. User clicks Yes to install
5. Progress dialog shows installation progress
6. Plugin loads after dependencies installed
This eliminates manual pip install steps for plugins!
