Add two comment-only clarifications to mxaccess_gateway.proto (no field/number changes): 1. MxEvent.replay_gap: states the sentinel is ONLY ever set on StreamEvents events and is ALWAYS unset on DrainEventsReply events, preventing Task 12 from accidentally emitting it on the drain path and removing any client ambiguity. 2. ReplayGap.oldest_available_sequence: clarifies that the value IS retained and replayable, and that a client resumes gap-free by setting after_worker_sequence = oldest_available_sequence - 1 in the next StreamEventsRequest (receiving events starting at oldest_available_sequence). Regenerated Generated/MxaccessGateway.cs (comment-only XML-doc change).
