x-randomvalues: declare NativeModules locally; resolve braces to @pezkuwi/braces

x-randomvalues read one export from react-native, NativeModules, and
took its types from the deprecated @types/react-native, which depends
on react-native itself: react-native 0.83, metro 0.83 and with them
image-size (open advisory, fixed only in 2.x, which metro 0.83 does not
accept). The two native modules it looks for are now declared in
src/react-native-modules.d.ts; the casts to RNExt are gone and each
module is checked before use. The published react-native.d.ts does not
reference react-native, and react-native/metro leave the dependency
tree.

braces resolves to @pezkuwi/braces 3.0.4: braces 3.0.3, the latest upstream release, has an open advisory with no fixed version (CVE-2026-93687, stack exhaustion through deeply nested patterns); the fork rejects nesting deeper than maxDepth (500) with a SyntaxError.
