The pointer/keyboard injector is host-lifetime (one EIS connection for every punktfunk/1
session), so its existing release_all only fires on EIS disconnect — never when a *client*
session ends. A button still down at an abrupt client disconnect therefore stayed latched in
the compositor: Mutter keeps the destroyed press's implicit pointer grab, so after reconnect a
stuck left-button-down turns every motion into a drag (windows move, text selects) while a
fresh click's press is swallowed — clicking buttons and text inputs does nothing. Only the one
held button is affected; keyboard and the other buttons are fine, exactly as reported.
Fix: input_thread now tracks the buttons/keys the client holds and, when the session ends,
synthesizes the matching up-events through the host-lifetime injector (whose EIS connection —
and the dangling grab — outlive the session). Backend-agnostic (normal inject path), so it
covers libei/EIS, wlr and uinput alike.
