A --proactivity flag is accepted and threaded through session creation, but its value is discarded before it has any effect.

A new --proactivity CLI flag has been added to the accepted-flags list, and a proactivityLevel field now flows through session creation, telemetry, and query dispatch. In this build the resolving function calls a stub that unconditionally returns undefined, so the flag's value is currently discarded before it has any effect.
