Revert warning suppression plugin to fix search functionality

- Removed suppress-search-warnings.js plugin that was breaking search
- Removed empty-module.js (no longer needed)
- Removed plugin configuration from docusaurus.config.ts
- Updated plugins README to remove documentation for deleted plugins

This reverts the warning suppression approach while keeping all visual improvements:
- Mobile search visibility enhancements remain intact
- Keyboard shortcuts (Cmd+K, Ctrl+K) functionality preserved
- All CSS improvements for search bar styling retained

The search functionality is now restored while maintaining the UI/UX improvements.

-## suppress-search-warnings.js
+## Currently Active Plugins
 
-This plugin suppresses webpack module resolution warnings that occur with the `@easyops-cn/docusaurus-search-local` plugin in Docusaurus v3.
+No custom plugins are currently active. The directory is maintained for future plugin development.
 
-### Background
+## Previous Plugins (Removed)
 
-The search plugin tries to import modules that don't exist in Docusaurus v3:
-- `../../utils/proxiedGenerated`
-- `../../utils/proxiedGeneratedConstants`
-- `./proxiedGenerated`
+The following plugins were previously used but have been removed as they interfered with search functionality:
 
-These imports were valid in Docusaurus v2 but have been removed in v3, causing harmless but noisy warnings during the build process.
+- `suppress-search-warnings.js` - Attempted to suppress webpack warnings but broke search functionality
+- `empty-module.js` - Helper module for the warning suppression plugin
+- `webpack-warning-filter.js` - Earlier attempt at filtering warnings (deprecated)
 
-### How it works
+## Note on Search Warnings
 
-The plugin uses multiple strategies to suppress these warnings:
-
-1. **Module aliases**: Sets problematic imports to `false` to prevent resolution
-2. **Module replacement**: Uses webpack's `NormalModuleReplacementPlugin` to replace missing modules with an empty module
-3. **Warning filters**: Filters out specific warning patterns from webpack's output
-4. **Stats configuration**: Configures webpack stats to ignore these warnings
-
-### Usage
-
-The plugin is automatically loaded via `docusaurus.config.ts`. No additional configuration is needed.
-
-### Alternative approaches
-
-If you prefer not to use the plugin, you can:
-
-1. Use the `build:quiet` npm script: `npm run build:quiet`
-2. Set NODE_OPTIONS environment variable: `NODE_OPTIONS='--no-warnings' npm run build`
-
-## empty-module.js
-
-A simple empty module used by `suppress-search-warnings.js` as a replacement for missing imports.
-
-## webpack-warning-filter.js (deprecated)
-
-An earlier attempt at filtering warnings. Kept for reference but not currently used.
+The `@easyops-cn/docusaurus-search-local` plugin may produce some harmless warnings during build about missing modules like `proxiedGenerated`. These warnings do not affect functionality and can be safely ignored.
