SearchBarTileSchema

Renders a search field: a Material Surface (extra-large shape, high surface container color) wrapping a single-line text field showing query, with placeholder when empty. The keyboard's IME action is always "Search".

Icons: leadingIcon is an arbitrary tile rendered in the leading slot. The trailing slot is shared: while query is empty it shows trailingIcon (if any); as soon as query has text it cross-fades to a built-in clear icon button, so a custom trailing icon is never visible at the same time as the clear button.

Query state: typing dispatches a local SearchBarTileEvents.OnQueryChanged and pressing clear dispatches OnQueryCleared; the holder applies both to its own state, so the text survives without a round trip to the server.

Triggers dispatched:

• OnQueryChangedEventTrigger — on every keystroke, with the new text as the event's incoming data. Pressing clear also fires it, with an empty string.

• OnQueryClearedEventTrigger — when the clear button is pressed, right before the query-changed trigger above.

• OnSearchEventTrigger — when the IME "Search" action is pressed, with the current query as the event's incoming data.

Notes: this is only the input field — it has no expanded state and shows no suggestion list. Render results yourself, e.g. by pairing it with a LazyColumn whose filterChildrenByTerm is driven by the query.
