📝 Walkthrough

Walkthrough

Added a conditional startup of the schedule runner in Vite's dev entry: when runtime task metadata exists (import.meta._tasks), it calls startScheduleRunner({}) to enable task scheduling during Vite dev execution.

Changes

Cohort / File(s)	Summary
Vite Dev Entry src/runtime/internal/vite/dev-entry.mjs	Imported startScheduleRunner from #nitro/runtime/task and added if (import.meta._tasks) { startScheduleRunner({}); } after WS setup and before exporting handleUpgrade. No exported signatures changed.
