feat(command): Command.Dialog closes on item select

Selecting an item ran its onSelect but nothing closed the dialog. Add a
provider-level `onSelect` to the soma command (fires for ANY item, on BOTH
paths — `selectCurrent` for the keyboard + the item `onclick` for the mouse,
after the item's own onSelect). The eidos `<Command.Dialog>` hooks it → `open
= false`.

Verified in-browser: click → closes; Enter → closes. check 0; command provider
tests 2/2.
