feat(gamepad): DualSense Edge backend — Linux UHID + Windows UMDF (N1)

Browse Source 
The plain-DualSense transport + report codec under the Edge USB identity
(054C:0DF2, verbatim 389-byte real-device descriptor cross-checked against
the raw usbmon capture + hhd's production virtual Edge), so the wire back
grips (BTN_PADDLE1..4: Deck L4/L5/R4/R5, Elite P1-P4) land on the Edge's
NATIVE buttons[2] bits instead of the fold/drop policy: PADDLE1/2 -> the
right/left back buttons, PADDLE3/4 -> the right/left Fn buttons (kernel
BTN_TRIGGER_HAPPY1..4 on >= 7.2; SDL/Steam read hidraw on any kernel).

- proto: Edge descriptor + btn2 bits + edge_paddle_bits(), pinned against
  hid-playstation DS_EDGE_BUTTONS_* and SDL_hidapi_ps5 (tests).
- Linux: DsUhidIdentity parameterizes the UHID create; DsEdgeLinuxProto /
  DualSenseEdgeManager. Headless-validated on .21 (7.1): driver=playstation
  binds 0DF2, all 4 input devices created, probe lightbar/player-LED
  feedback round-trips; dualsense-test grew --edge (cycles all 4 paddles).
- Windows: UMDF driver serves device_type=2 (Edge descriptor/attrs/strings,
  DS feature blobs); WinDsIdentity parameterizes the SwDevice profile +
  devtype stamp; DsEdgeWinProto / DualSenseEdgeWindowsManager; INF gains
  pf_dualsenseedge. Driver change => resign + reinstall before on-glass.
- Router: DualSenseEdge arms in route_handle/apply_rich/pump/heartbeat;
  pick_gamepad folds Edge -> itself on linux||windows; degrade_if_no_uhid
  covers it.
- Client (SDL): 054C:0DF2 declares DualSenseEdge (no distinct SDL type);
  Edge physical pads take the raw DS5 effects path; console-UI glyphs =
  Shapes. Apple/Android pickers follow separately.

Verified: .21 clippy -D warnings + 292/0 host tests + on-box UHID bind
smoke; .133 clippy pending in this push.
