On iOS the system text-selection menu (Copy / Look Up / Translate /
Share) appeared on top of Readest's annotation toolbar. The previous
workaround removed and re-added the selection range on a timer
(makeSelectionOnIOS) to shake the menu off — flaky on iOS 16 and on the
first long-press of a word.
Suppress the menu natively instead, in the native-bridge iOS plugin.
ContextMenuSuppressor swizzles WKContentView so non-editable web
selections produce an empty menu that is never presented:
* editMenuInteraction(_:menuForConfiguration:suggestedActions:) — the
UIEditMenuInteraction delegate WebKit uses to build the menu on
iOS 16+ (the menu users actually see on modern iOS).
* presentEditMenu(with:) — a present-time backstop.
* canPerformAction(_:withSender:) — the legacy UIMenuController gate
for iOS 15 and earlier.
Editable HTML fields keep their native menu (Paste / Select All still
work) via a cut:/paste: probe. Text selection and drag handles are
unaffected, so the annotation toolbar still triggers.
With suppression handled natively, makeSelectionOnIOS is removed and iOS
selections take the same path as desktop.
Closes #4218
