Package production dependencies per architecture for online and offline upgrades.
Validate dependencies and isolated backend startup before readiness, repair once
when permitted, and preserve service/data through failed preparation or rollback.
Publish release bundles with master images and expose an opt-in develop build
sharing the development index across Alpine and Debian images.
Preserve supported expression fields instead of stringifying them, and probe individual fields only when whole-expression validation fails. Convert unsupported syntax and weekday ranges ending in 7 while preserving legacy date/weekday rules and valid OR branches.
Add execution regressions for issue #3099 and 64 calendar boundary cases in UTC and Asia/Shanghai. Ensure timezone child tests actually run under the Node test runner.
Validation: 745 tests passed, 8 skipped; final targeted regressions passed; backend compilation passed. Differential calendar checks matched 142,360 execution timestamps.
Fixes#3099
* refactor: migrate cron scheduling to node-cron
* feat: support annually midnight and minutely cron macros
* fix: harden cron recovery and system scheduler compatibility
