- Handle retry API "not in an error state" responses by refreshing the server session instead of failing immediately
- Restore the correct view state for generating, awaiting_input, complete, and error sessions during retry recovery
- Reconnect planning/interview/subtask streams only when needed while preserving in-flight output and history
- Add regression tests for connection-loss retry recovery across PlanningModeModal, MissionInterviewModal, and SubtaskBreakdownModal
