Overview

Wraps the agent block with the server's error boundary:

NoMatchingPatternError -> A2A::UnsupportedOperationError, so an
unhandled operation falls out of `case ... in` with no else branch
A2A::Error             -> returned for the binding layer to format
anything else          -> logged, returned as a JSON-RPC internal error
