Pull request overview

This PR backports updates to the Exchange::IMessageControl interface to align it with newer Thunder messaging metadata and JSON-RPC generation expectations.

Changes:

• Replaces the local messagetype enum with Core::Messaging::Metadata::type and adds a JSON annotation/version line.
• Switches interface method return types from uint32_t to Core::hresult.
• Adds a Modules() property and changes Controls() to be module-indexed (module-specific controls).
