/**
|

* Schedules — Cron Job Management Surface (v0.1.0)
|

*
|

* Wraps the kernel /api/v1/schedules API. No Starlark backend —
|
||
* this surface talks directly to the core scheduled-tasks endpoints.
|
||
*
|
||
* SDK usage:
|
||
* sw.shell.Topbar — standard navigation bar
|
||
* sw.ui.* — primitive components
|
||
* sw.api.* — raw REST calls to /api/v1/schedules
