Subject: [PATCH] fix: migrate middleware.ts to proxy.ts for Next.js 16
 compatibility
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Next.js 16 deprecated the `middleware` file convention in favour of `proxy`.
The deprecated `middleware.ts` was causing MIDDLEWARE_INVOCATION_FAILED 500
errors on every request hitting repofuse.com.

Changes:
- Rename middleware.ts → proxy.ts (required by Next.js 16)
- Return NextResponse.next() explicitly instead of bare `return` (undefined
  is not a valid response in the Edge runtime and triggers the 500)
- Wrap auth.protect() in its own try/catch to redirect gracefully on Clerk
  auth failures rather than surfacing an unhandled exception
- Add outer try/catch so any unexpected error redirects cleanly instead of
  propagating as a 500
