Add custom parser for props["pluginctl"] with ignore assets support

- Add PluginCtlConfig struct with IgnoreAssets field for glob patterns
- Add ParsePluginCtlConfig function to parse manifest props["pluginctl"]
- Update updateassets command to respect ignore patterns with glob matching
- Add comprehensive logging when files are skipped due to ignore patterns
- Support patterns like *.test.js, build/, node_modules for flexible exclusion
- Add extensive tests for config parsing and path matching functionality
- Maintain backward compatibility with existing manifests
- Fix Makefile check-changes target and add logger init to tests
