Aligns the Karaoke dock with the ASMR dock’s Role → Room mode → Configure → Live flow.
Restores Create Room after browser authorization and makes account checks deterministic.
Reuses saved installation authorization instead of reopening the browser unnecessarily.
Shows visible setup and room-creation errors in the dock.
Uses the relay endpoint returned by the Control Plane.
Correctly reads account-scoped Discord room availability.
Keeps local-relay hosting available without hosted-relay entitlement.

The ASMR and vScene installers are rebuilt at the unified 0.1.5 suite version; their product behavior is unchanged from 0.1.4.
