feat(gwolves): add HTX Ultra driver (wired + wireless)

[defendercf]

Protocol

The protocol was captured live from the official G-Wolves web driver at
mouse.fit (patching HIDDevice.prototype.sendReport/inputreport in the
browser console), then independently reproduced with hidapitester with
no browser involved. It's the same shared VGN-family reference design
already implemented for the VGN Dragonfly F2 Master+ and the Pulsar 4K
Wireless Receiver — 16-byte packets on output report 8:

• Read: opcode 0x08, Write: opcode 0x07, at a 16-bit address
• Packet checksum: 85 - sum(bytes[0..14]) - reportId
• Payload checksum: 85 - sum(precedingPayloadBytes) (confirmed on every
  captured packet, DPI/LOD/all 7 polling rates)
• DPI: 4-byte stage entries, 50-DPI steps, (dpi/50)-1 encoding
• Polling rate: period-in-ms for ≤1000Hz, one-hot bit flags above (see
  PROTOCOL-NOTES.md, attached below, for the full derivation)
• LOD: Low=3, Medium=1, High=2 (firmware's own non-sequential ordering,
  confirmed by capturing all three)

Changes

• src/gwolves/index.ts - new protocol module (own implementation, not
  importing vgn's, matching the Pulsar/VGN precedent)
• src/drivers/gwolves/hid.ts - new driver, model-agnostic
• src/drivers/gwolves/products.ts - product catalog (HTX Ultra wired
  0x5618 + wireless receiver 0x3854, both verified: true)
• src/drivers/gwolves/hid.test.ts - 4 tests, device recognition
• src/drivers/gwolves/protocol.test.ts - 6 tests, against real captured
  packets
• src/drivers/vendors.ts - added gwolves 0x33e4 + two HID filters
• src/drivers/registry.ts - registered driver
• package.json / src/index.ts - ./gwolves export

Wireless quirk: the mouse must be actively awake (recently moved) to
accept config writes over the 2.4GHz receiver — writes sent while idle
are silently ignored. Noted in the driver and surfaced in the
setPollingRate error hint.

One thing worth flagging: src/drivers/mouse-types.ts already had
"G-Wolves" in its brand union before this PR, with no implementation
behind it. Not sure if that's leftover scaffolding or related to other
in-progress work — happy to coordinate if there's context I'm missing.

Testing

Build passes cleanly. All 517 tests pass (npm run [check).
