可乐小猫 2fed0f09bb Fix infinite recursion in web crypto randomUUID polyfill (#858 )

On web (browser/Electron), expo-crypto's randomUUID() and getRandomValues()
just forward to globalThis.crypto.* (see expo-crypto/src/ExpoCrypto.web.ts).
The previous polyfill installed `g.crypto.randomUUID = () => ExpoCrypto.randomUUID()`,
which on web reads back through the same `globalThis.crypto.randomUUID` it
just installed, recursing until the stack overflows. The same trap exists
for getRandomValues, but it rarely triggers because the native version is
almost always present.

Capture a bound reference to the native getRandomValues *before* installing
the polyfill, and generate UUID v4 in JS from 16 random bytes (RFC 4122
version + variant bits). The fallback path stays on ExpoCrypto.getRandomValues
(non-recursive on native), and ExpoCrypto.randomUUID is no longer used.
