fix: preserve full language rows when filtering picker

 The footer shows the current language pair (initially **English → Japanese**). Click it or open **Actions** with Command-K to change the source language, change the target language, or swap them. Source and target selection use Conjure's themed popup, not a native menu. Fuzzy-search language names (for example, `jpns` matches **Japanese**), scroll the full list, and select with Up/Down, Control-J/K, and Return or by clicking a language. A checkmark marks the current language; it is selected and scrolled into view when the picker opens. Escape, Back, Command-K, or clicking outside cancels the picker without changing languages or leaving Translate. Language choices are saved locally and apply to both providers. Changing languages clears the previous result without submitting another request. The input hint and output accessibility label follow the selected pair. Escape closes an open picker first and dismisses the window only when no picker is open. Back closes the picker first, then returns from the context step to editing the original text (discarding context), then returns to the launcher and restores your search. Command-W always dismisses the entire window.
 
+The language picker resizes to complete rows as results are filtered, showing up to six rows before scrolling.

 Editing the input, changing languages or providers, saving or forgetting the key in Settings, or leaving Translate cancels the active request; cancelled results are not shown. After a request fails, submit again to retry.
