* **Framework Migrations**: Upgrades deprecated APIs (e.g., Pages Router to Next.js App Router, or fetch to TanStack Query).
* **Performance & Cleanup**: Identifies unmemoized computations, dead code, and memory leaks.
* **AST Integrity**: Validates every refactored file against TypeScript syntax trees before saving.
