* fix(macos): forward back/forward mouse buttons in capture and emulation
OtherMouseDown/Up events on macOS carry a button number field that
distinguishes middle (2), back (3), and forward (4) buttons. The
capture backend was unconditionally mapping all OtherMouse events to
BTN_MIDDLE, silently dropping back/forward. The emulation backend had
no match arms for BTN_BACK/BTN_FORWARD, causing them to be dropped
with a warning.
Fix capture by reading MOUSE_EVENT_BUTTON_NUMBER and mapping 3->BTN_BACK,
4->BTN_FORWARD. Fix emulation by adding match arms for BTN_BACK/BTN_FORWARD
and setting MOUSE_EVENT_BUTTON_NUMBER on the emitted CGEvent so macOS
apps receive the correct button identity.
* fix(macos): track button state and double-clicks by evdev code instead of CGMouseButton
Back, forward, and middle buttons all map to CGMouseButton::Center on
macOS, which caused them to share a single pressed-state boolean and
alias in double-click detection. Replace the ButtonState struct with a
HashSet<u32> keyed by evdev button code so each button is tracked
independently.

* reference count capture
Multiple captures can now be created at the same position.
Captures at the same position are reference counted.
* update testcase
will be required by #200 / #164
* Input capture and emulation can now be disabled and will prompt the user to enable again.
* Improved error handling to deliver more useful error messages
