ExceptionHandler class

Handles exceptions raised in the application and returns standardized error results.

This class provides comprehensive exception handling with:

• Automatic RFC 7807 Problem Details mapping
• Request context inclusion in error reports (if available)
• Development vs production error detail levels
• Custom error mapping

The handler is protocol-agnostic and returns an ErrorResult which can be formatted by the transport layer (HTTP, Socket, etc.).
