- * This query captures various TypeScript and React component definitions in TSX files.
+ * This query captures various TypeScript and React component definitions in TSX files,
+ * as well as advanced TypeScript language constructs.
+ *
+ * SUPPORTED LANGUAGE CONSTRUCTS:
+ * - React Components (Function, Arrow, Class)
+ * - Higher Order Components
+ * - JSX Elements and Expressions
+ * - React Hooks
+ * - Context Providers/Consumers
+ * - React-specific Decorators
+ *
+ * Note: Generic TypeScript constructs like Utility Types, Async Functions,
+ * Class Members, Enums, and Namespaces are defined in typescript.ts
