Send a raw DevTools-protocol command to the browser page on a device and return its reply — the escape hatch for capabilities no dedicated tool wraps yet (Emulation, Performance, CSS, Animation, DOM mutation, …). Works on BOTH iOS Safari and Android Chrome, auto-detected from the udid. `method` is "Domain.command" (e.g. "Emulation.setGeolocationOverride"); `params` is that command's parameter object. Scope is the BROWSER — this reaches web content only, never the device or native apps. Prefer a dedicated tool when one exists: they handle setup ordering, lifecycle and teardown that a bare command does not. IMPORTANT, iOS: the two engines do NOT implement the same protocol — Android is full CDP, iOS is WebKit's dialect. Chrome-only domains fail with -32601 "domain was not found" (Accessibility, Emulation, and Page.captureScreenshot are all absent on iOS), and a `*.enable` on iOS reports success without proving the domain exists, so never treat it as a capability probe — probe with a real method.
