Refining a plan (or submitting any input) while the session had no active
question — e.g. after a failed retry cleared summary/currentQuestion —
threw InvalidSessionStateError("No active question in session") at the
operator. Now the interview continues instead:
- The refine and contextual-comment branches no longer require
session.summary; they fall back to a running summary rebuilt from
persisted history.
- A submission with no active question reprompts the agent via
formatQuestionRegenerationForAgent to produce a fresh option-driven
question, carrying the submitted operator input along as context.
- The Planning modal forwards no-question submissions to the server
(loading view + SSE) instead of dead-ending with a local error.
