fix: display session ID after CLI invoke completes (#957)

* fix: display session ID after CLI invoke completes (closes #664)

The streaming and non-streaming invoke responses include a session ID
from the runtime, but the CLI paths discarded it. Now prints the
session ID and a resume command hint after invoke output.

* fix: include sessionId in AGUI protocol invoke result
