Leave the shell restart to the update flow

Restarting immediately after the plugin rescan races Quickshell IPC handler creation and can crash the exiting shell. The normal update flow already restarts after migrations. Let this migration finish through live enablement and placement without adding timing workarounds.

-Elsewhen (`omacom.elsewhen`) ships in the `elsewhen` package at `/usr/share/omarchy/plugins/omacom.elsewhen`. A symlink in `~/.config/omarchy/plugins/` makes it available to the shell. New installs place it immediately before the clock; the migration uses `omarchy bar put omacom.elsewhen --before omarchy.clock`, which preserves an existing placement and uses Elsewhen's normal right-side placement if the clock is absent.
