Correct Dual VoT update checks
- Uses this repository's main or dev metadata in the in-app About screen.
- Stops upstream Morphe versions without the -dualvot.* suffix from producing false update notifications.
More resilient scheduled updates
- Gives the two staggered cron deliveries independent concurrency groups so a runner-queue stall in one slot cannot block the fallback slot.
- Keeps manual synchronization runs serialized.
Validation
- 23 focused source and updater regression tests passed.
- PR build 34752116296 completed successfully.
- Release build 34752262993 completed successfully.
- CI-built MPP manifest reports version 1.42.0-dualvot.8.5.2.
