+Fixed macOS `TextField` wrapping to multiple lines when its text was wider than
+the field. `perry-ui-macos`'s `create()` built the field from
+`NSTextField::textFieldWithString`, whose cell wraps and grows, and never
+overrode it — so a fixed-width field grew tall instead of scrolling, unlike
+every other backend. The cell is now configured for single-line editing
+(`usesSingleLineMode`, `scrollable`, `wraps = false`, clipping line-break mode),
+matching iOS / GTK4 / Android / Windows. Multiline input keeps its own widget,
+`TextArea`.
