Add type-aware TypeScript ESLint rules for RN

[kieran-osgood-shopify]

What changes are you making?

• Move the React Native ESLint config into platforms/react-native/.eslintrc.cjs so type-aware linting resolves the workspace tsconfig.json consistently from filtered package lint scripts.
• Enable @typescript-eslint/parser with parserOptions.project and add @typescript-eslint/require-await.
• Keep the existing React Native lint rules for type imports, shadowing, and console usage.
• Ignore the sample app native android/ and ios/ directories during sample ESLint runs.

How to test

• shadowenv exec --dir . -- /opt/dev/bin/dev react-native lint module
• shadowenv exec --dir . -- /opt/dev/bin/dev react-native lint sample

We're using oxlint for web. Worth considering for RN too?

[kieran-osgood-shopify]

I'm up for consistency and oxlint seems to have much better support than the last time i tried it so at least we wont lose out too much on the ts lint rules anymore (trying to remember the issues I had last time)

Benefit is gonna be mostly unification as library code is so small that the speed difference isn't going to save more than 10 second, our lint and tsc checks only take around 12s
