Cx API:

- Add HideClipboardActions
- Cross-platform API ready for iOS implementation
Android Implementation:
- Native ActionMode integration with floating toolbar (API 23+)
- JNI bindings for showing/hiding menu and handling clipboard actions
- Event system for Copy/Cut/Paste/Select All actions
- Smart menu state management based on selection and clipboard
TextInput Integration:
- Long press selects word and shows menu
- Double tap and long press selects word and shows menu
- Selection preservation when tapping selected text
* Fix button clicks during keyboard dismissal on mobile
When tapping a button while the keyboard is visible on iOS/Android, the keyboard dismisses and shifts the layout mid-press. This caused the event system to treat the finger as no longer "over" the button, preventing the click from registering.
Fixed by treating taps as "over" if the finger didn't move significantly, even if the widget moved underneath due to layout shifts.
* Make is_over conditionals clearer
* Ensure that LongPress (LongClick) on Android properly uses touch slop
Previously, we assumed that multiple touch action events would occur
before a LongClick, but that is not necessarily true.
It is possible to just have one down touch immediately followed by a
LongClick, so we now account for that.
This also fixes the tracking of touch event locations such that
stale values aren't accidentally used when calculating if a finger movement
exceeded the allowable touch slop for considering a touch as a long press.
(Rust would've caught that... thanks Java)
* remove excess log stmt
