feat(FN-1218): harden mission autopilot with self-healing recovery

- Add mission self-healing project settings for stale activation thresholds, task retry budgets, and mission health-check intervals
- Extend MissionAutopilot with failed-task retry handling, blocked feature escalation, stale activating mission recovery, and periodic feature/task consistency reconciliation
- Wire autopilot failure and recovery flows through Scheduler and InProcessRuntime, including startup recovery for watched missions after crashes
- Add blocked feature status support in core mission types and CLI mission status labels
- Expand mission-autopilot coverage for retry flows, stale/startup recovery, health checks, and regression scenarios, and include a patch changeset for @gsxdsm/fusion
