Subject: [PATCH 1/2] Forward right/middle mouse drags to Ghostty for
 mouse-reporting apps

cmux overrode mouseDragged (left button) but not rightMouseDragged or
otherMouseDragged, so pointer motion during a right- or middle-button drag
was never forwarded to libghostty. Under an app that enables mouse reporting
(e.g. tmux), this broke the right-click context menu: right-press opened it,
but dragging to a menu item produced no hover highlight and release selected
nothing. Add both overrides, funneling to mouseDragged the same way upstream
Ghostty funnels every drag variant to one position-forwarding path.
