razer: add Cobra wired mouse support (hardware-verified)

[jazzstack]

Summary

Adds support for the Razer Cobra wired mouse (1532:00a3) through a new dedicated driver in @openmouse/protocol (RazerCobraHidClient), plus the control wiring, device art, a preview fixture, and the CI install fixes needed to fetch the protocol package.

Hardware-verified by an owner of the device. The confirmed command table lives in docs/razer-testing.md in the protocol repo.

What's included

• Protocol — dedicated RazerCobraHidClient in src/drivers/razer/cobra-hid.ts. Covers effects and colour only, no brightness. Reads answer on transaction id 0xff; extended-matrix effect writes answer on 0x1f, including breathing (OpenRazer lists breathing on 0x3f, which the hardware does not match). DPI 100–8500, polling 125/500/1000 Hz, single Logo LED zone.
• Control wiring — RazerCobraHidClient is accepted and activated like the other Razer clients.
• Device art — 1532:00a3 maps to /devices/razer-cobra.webp.
• Preview fixture — ?preview=razer-cobra renders the Cobra status.
• Build fixes — the protocol git dependency is fetched over HTTPS and npm's allow-git policy is set to all, so CI (Vercel) can install the protocol package under npm 11's security defaults.

Base commits

This branch also carries four earlier commits from dev (custom colour picker tab, viper mini device art, bundle budget raise) that the Cobra work sits on top of.

Testing

• Protocol: 275 tests pass, including 6 new Cobra tests.
• App: tsc --noEmit, vite build, and all 32 tests pass.
• Verified on hardware: DPI read/write with persistence, polling read/write at 125/500/1000 Hz, and every effect mode on 0x1f (including breathing).
