Bug A — navigation no-op: replace $app.calendarState private-API poking
with the official @schedule-x/calendar-controls plugin. CalendarShell
creates the plugin once via useState stable initialiser and passes it to
ViewToolbar as `controls`. ViewToolbar calls controls.setDate(PlainDate)
and controls.setView(id) for all navigation and view-switching. Step size
matches the active view: day→±1 day, week→±1 week, month-*→±1 month.
Bug B — popover-open calendar flash: replace the unselected
useCalendarStore() destructuring in CalendarShell and ViewToolbar with
per-field selectors. Neither component now subscribes to openEventId, so
popover open/close no longer triggers a re-render that rebuilds the
Schedule-X config.
- Add @schedule-x/calendar-controls@4.6.0 dependency
- Update CalendarShell.test.tsx: add vi.mock for calendar-controls
- typecheck, vitest (37/37), build all pass
