Pull request overview

Updates the Discovery watchedV2 API to be fire-and-forget (no return payload), aligning the C++ interface/implementation, tests, demo output, and OpenRPC fixtures with a void/null result.

Changes:

• Change Discovery.watchedV2 return type from Result<bool> to Result<void> and switch implementation from helper_.get(...) to helper_.invoke(...).
• Update unit/component tests and the API demo app to stop expecting a boolean result.
• Update OpenRPC fixtures to define a null result schema and null example values for watchedV2.
