feat(CommandTextArea): add component

[tenphi]

Note

Medium Risk
Refactors ComboBox popover/filtering shared with a new field component; keyboard commit and filtering semantics changed in ways covered by tests but worth regression-testing ComboBox consumers.

Overview
Introduces CommandTextArea, a multiline field that keeps focus in the textarea while showing a virtual-focus list popover for configurable triggers (default line-start / commands or @-style tokens). Options insert their textValue, fire onCommand, and can match/highlight across textValue, plain-text children, and description; the popover is positioned at the caret via a mirror-measurement hook.

ComboBox no longer owns its inline overlay: shared ListBoxPopover (plus useCompositeFocus, list navigation, and filterCollectionNodes) drives the popover for both components. Filtering defaults to textValue only again for ComboBox; CommandTextArea opts into extra fields with matchExtraFields. ListBox / Item gain optionHighlight / description highlighting for search matches.

Follow-up fixes in the same change: virtual focus and Enter/Tab commit stay aligned with the visible filtered list; stable listStateRef hooks; caret resync and defaultValue for uncontrolled mode; docs, stories, tests, and a small bundle size-limit bump.
