fix: prevent premature Quick Prompt completion from setup events

The session emits completion signals (agent-activity:completed,
message-complete, status:idle) during initialization before any
response content arrives. These early events were incorrectly
transitioning the popup to 'complete' phase, causing the
Nothing → In Progress → Nothing cycling pattern.

Track whether response content has been received via a ref and
only transition to 'complete' when hasContentRef is true. This
ensures setup/init completion events are ignored and the popup
stays in streaming until actual content has arrived and a
terminal event follows.
