Command Palette with Argument Chips
Comandos que recebem argumentos ali mesmo, viram chips, e uma lista que se mede antes de mudar de altura.

/**
* A command palette whose commands take arguments, filled in place.
*
* The hard part is not the list, it is focus. "Assign to [person] with
* [priority]" is a small form, and the obvious build gives every picked value
* its own focusable element. Tab order, Backspace and screen-reader context all
* fracture halfway through the command. So building a command never adds a tab
* stop: the input is the only one, however deep the command goes. Only the
* footer's two buttons sit beside it, and they are always the same two.
*
* Picking a command collapses it into a chip painted before the input. The
* chip is render output, not a field. The list slides to that command's first
* argument and the same input now filters its options.
*
* Filling the last argument stages the command as a clause rather than
* running it, and the list slides back to what is left, joined by an "and".
* One session builds a compound. Nothing runs until Apply.
*
* Backspace on an empty query pops the last chip, across the "and" too. Chips
* never enter the tab order but are clickable: clicking one rewinds to that
* argument, and the tail dims first to show how much the rewind will take.
*
* Matching is a scored subsequence, so "mvp" finds "Move to project", with
* bonuses for word starts and adjacency and a penalty for gaps. The list's
* height is measured in pixels and eased, because `auto` does not animate.
