feat(razer): add individual LED lighting for Diamondback Chroma

[DEERSTUDIO101]

The Diamondback Chroma (1532:004c) currently offers only whole-mouse lighting effects. Add LED 0 through LED 20 to the existing lightingZones interface so the OpenMouse lighting card can set a color or turn off each cell independently.

Use OpenRazer's model-specific single-row frame write (0x03/0x0c, transaction 0xff) and volatile custom-effect activation (0x03/0x0a). Each edit uploads only the selected cell. Serialize lighting writes, keep unchanged cells out of the payload, and cache only acknowledged writes. Whole-mouse effects and global brightness remain available. No Bridge changes are required.

Protocol sources and a hardware validation checklist are in docs/diamondback-custom-lighting.md. LED numbers are protocol indices; their physical positions and the new commands still need confirmation on a Diamondback. This does not enable Mamba Elite custom lighting or button remapping.

Validation:

• Strict TypeScript build and package generation passed.
• Focused Razer driver and custom-frame tests: 58 passed, including invalid indices/colors, refused writes, switching effects and concurrent cell writes.
• OpenMouse built against the locally packed library: build and all 292 tests passed.
• The full local Windows protocol suite is not reported as passing: existing Corsair assertions expect English number formatting and fail under de-DE; the registry's exhaustive probe did not complete. Those files are unchanged by this PR.
• Hardware verification and visible Chrome testing remain pending.

Companion preview: OpenMouse-Project/openmouse#692. OpenMouse's existing protocol-update workflow can adopt the released package after this change is merged and published.
