* feat(plugin): implement SPI-based plugin discovery and management API
Refactor plugin discovery to use SPI pattern and add REST API for plugin control:
SPI-based Discovery:
- Replace hard-coded plugin discovery with PluginProvider SPI pattern
- Add comprehensive tests for UnifiedPluginManager and PluginStatePersistence
- Enable automatic plugin registration for better extensibility
Management API:
- Add PluginControllerV3 with 5 endpoints (list, detail, status, config, availability)
- Create PluginInfoVO and PluginDetailVO for API responses
- Create PluginStatusForm and PluginConfigForm for API requests
- Integrate plugin state checking into all plugin managers
- Add getAllPlugins() methods to expose plugin registries
- Fix core module dependency name for custom-environment-plugin
* fix: UT failed
* fix: UT failed
* refactor(plugin): extract PluginStatePersistence to interface-based design
* fix(plugin): remove auth plugin from critical list to allow custom auth
* feat(plugin): implement config-driven default status for exclusive plugins
