FN-6509: show resumable subtask progress
Subtask breakdowns now show live progress immediately and remain resumable after closing.
- Add startup and reconnecting progress states with empty-thinking feedback.
- Preserve generating and editing subtask sessions for background resume instead of canceling on close.
- Cover mobile, desktop, running, awaiting-input, and completed resume flows in modal tests.
- Document resumable subtask generation behavior and add localized strings.
