fix: allow middleware to override error responses with redirects

[surajkewat72]

This change enables middleware to handle errors gracefully by allowing them to return redirect responses even after the error handler has been invoked. Previously, when an error occurred in a downstream handler, the error handler's response would be set and finalized, preventing middleware from providing alternative responses like redirects.

The fix adds an additional condition in the compose function to check if there's an error and the returned response is different from the current context response. This allows middleware to override error responses while maintaining backward compatibility.

Fixes #4530

The author should do the following, if applicable

• Add tests
• Run tests
• bun run format:fix && bun run lint:fix to format the code
• Add TSDoc/JSDoc to document the code
