feat(gamepad): add virtual Xbox One/Series + DualShock 4 pad types

Extends virtual-controller support beyond Xbox 360 + DualSense. Goal: a
physical Xbox One or PS4 pad on the client gets a near-native matching virtual
pad on the host, auto-resolved from the controller type.

Protocol/core:
- GamepadPref gains XboxOne (wire 3) + DualShock4 (wire 4); to_u8/from_u8/
  from_name/as_str + C ABI PUNKTFUNK_GAMEPAD_XBOXONE/_DUALSHOCK4 constants
  (compile-time guard ties them to the enum). Single-byte wire form is
  unchanged, so it's forward-compatible (older peers degrade to Auto).

Host (Linux):
- New UHID DualShock 4 backend (inject/dualshock4.rs) bound by hid-playstation:
  lightbar, touchpad, motion, rumble — DualSense minus adaptive triggers /
  player LEDs / mute. Reuses the DualSense pure state + button mapping; only the
  report byte layout, the real-DS4 HID descriptor, the GET_REPORT handshake
  (0x12 MAC mandatory; 0x02 calibration; 0xa3 firmware) and the touchpad
  resolution (1920x942) differ. Touchpad/motion ride the existing 0xCC plane,
  lightbar the 0xCD Led plane (deduped); rumble the universal 0xCA plane.
- Xbox One/Series is the uinput Xbox-360 backend parameterized with the One S
  USB identity (045e:02ea) for matching glyphs — XInput-identical otherwise.
- PadBackend dispatch + resolver handle both; off Linux the UHID pads and
  One/Series fold into Xbox 360. Windows-host DS4 (ViGEm) deferred.

Clients (auto-resolve physical pad -> virtual type, plus manual settings):
- Linux/Windows (SDL3): SDL_GAMEPAD_TYPE_PS4 -> DualShock 4, _XBOXONE ->
  Xbox One; PadInfo carries the resolved pref; DS4 touchpad/motion capture +
  lightbar already type-agnostic. Linux settings combo + label updated.
- Apple (GameController): GCDualShockGamepad/GCXboxGamepad detection, DS4
  touchpad capture, settings picker entries.
- Android (Kotlin): InputDevice VID/PID auto-detect (matching the other
  clients) + settings entries.
- probe: --gamepad help/aliases.

Also hardens the Android JNI boundary: wrap the teardown + poll-thread shims in
catch_unwind so a panic degrades to a logged no-op instead of aborting the app.
