refactor(cursor-rules): restructure rules architecture with meta-rule system

- Reorganize cursor rules into logical domain-based directories - Implement meta-rule system for workflow-specific rule bundling - Move core rules to dedicated /core directory - Consolidate development rules under /development namespace - Add architectural patterns and implementation examples - Create workflow-specific meta-rules for common development tasks - Remove deprecated standalone rule files - Update package dependencies for new rule structure BREAKING CHANGE: Cursor rules file structure has been reorganized Files moved from root rules directory to domain-specific subdirectories

 ### 1. Worker Thread Requirements

 - All SQL operations MUST be performed in a worker thread
+
 - Main thread should only handle worker initialization and communication
+
 - Never block the main thread with database operations

 ### 2. Code Organization

 - Keep worker code in separate files (e.g., `*.worker.js`)
+
 - Use ES modules for imports/exports
+
 - Follow the project's existing module structure

 ### 3. Required Headers
@@ -46,14 +54,18 @@ absurd-sql/
 When developing locally or deploying, ensure these headers are set:

 ```
+
 Cross-Origin-Opener-Policy: same-origin
 Cross-Origin-Embedder-Policy: require-corp
+
 ```

 ### 4. Browser Compatibility

 - Primary target: Modern browsers with SharedArrayBuffer support
+
 - Fallback mode: Safari (with limitations)
+
 - Always test in both modes

 ### 5. Database Configuration

 Recommended database settings:

 ```sql

 ### 6. Development Workflow

 1. Install dependencies:

   ```bash
+
   yarn add @jlongster/sql.js absurd-sql
+
   ```

 2. Development commands:
+
   - `yarn build` - Build the project
+
   - `yarn jest` - Run tests
+
   - `yarn serve` - Start development server

 ### 7. Testing Guidelines

 - Write tests for both SharedArrayBuffer and fallback modes
+
 - Use Jest for testing
+
 - Include performance benchmarks for critical operations

 ### 8. Performance Considerations

 - Use bulk operations when possible
+
 - Monitor read/write performance
+
 - Consider using transactions for multiple operations
+
 - Avoid unnecessary database connections

 ### 9. Error Handling

 - Implement proper error handling for:
+
  - Worker initialization failures
+
  - Database connection issues
+
  - Concurrent access conflicts (in fallback mode)
+
  - Storage quota exceeded scenarios

 ### 10. Security Best Practices

 - Never expose database operations directly to the client
+
 - Validate all SQL queries
+
 - Implement proper access controls
+
 - Handle sensitive data appropriately

 ### 11. Code Style

 - Follow ESLint configuration
+
 - Use async/await for asynchronous operations
+
 - Document complex database operations
+
 - Include comments for non-obvious optimizations

 ### 12. Debugging

 - Use `jest-debug` for debugging tests
+
 - Monitor IndexedDB usage in browser dev tools
+
 - Check worker communication in console
+
 - Use performance monitoring tools

 ### Common Issues

 1. SharedArrayBuffer not available
+
   - Check COOP/COEP headers
+
   - Verify browser support
+
   - Test fallback mode

 2. Worker initialization failures
+
   - Check file paths
+
   - Verify module imports
+
   - Check browser console for errors

 3. Performance issues
+
   - Monitor IndexedDB usage
+
   - Check for unnecessary operations
+
   - Verify transaction usage
