Hot Reload for Routes

[CodeMaverick-143]

Restarting the server manually after every route change slows down development.

Technical Implementation:

• Integrate a file watcher (like chokidar) in the development server.
• When a route file changes, clear the require/import cache for that file.
• Re-register the routes in the running App instance without killing the process.

---

Acceptance Criteria:

• Modifying a route handler file automatically updates the behavior on the next request without a manual restart.
• Console logs indicate that a reload has occurred.
