fix: minor cleanup

[ErnestM1234]

Greptile Summary

This is a minor cleanup PR for the gt-react-native package that fixes several small issues: incorrect import paths in the example app, a duplicate setLocaleWithoutPersist call, leftover scaffold code (multiply), and adds SSR guards for localStorage access. The console.log on polyfill success is also removed, aligning with the repo's no-debug-logging policy.

Confidence Score: 5/5

Safe to merge — all changes are straightforward bug fixes and cleanup with no functional regressions.

No P0 or P1 issues found. All changes are correct: import path fixes, duplicate-call elimination, SSR guard additions, scaffold removal, and removal of debug logging. The dependency array change in useEffect (dropping the non-memoized setLocaleWithoutPersist) is correct and prevents a potential infinite re-render loop.

No files require special attention.

Important Files Changed

Filename	Overview
packages/react-native/src/utils/nativeStore.ts	Added SSR guard for localStorage in both nativeStoreGet and nativeStoreSet, warning and returning early when running in a server-side environment where localStorage is unavailable.
packages/react-native/src/provider/hooks/locale/useDetermineLocale.ts	Removed duplicate setLocaleWithoutPersist(newLocale) call, removed it from the useEffect dependency array (it's a non-memoized function ref), and switched the unsupported locale warning to the shared createUnsupportedLocaleWarning helper.
packages/react-native/src/tools/testLocalePolyfill.ts	Removed console.log on polyfill success path (aligns with no-debug-logging rule) and simplified catch (e) to catch across all 8 Intl try/catch blocks.
packages/react-native/src/index.tsx	Removed leftover scaffold multiply function and its associated GtReactNative import, which were never part of the intended public API.
examples/react-native/src/App.tsx	Fixed incorrect import paths from '../src/_gt/...' to './_gt/...' — the file is already inside src/, so the old paths pointed to a non-existent src/src/_gt/ directory.
packages/react-native/STYLE_GUIDE.md	New architecture and style guide documenting native module rules, export entry points, persistence patterns, and common pitfalls for the gt-react-native package.
packages/react-native/src/errors-dir/warnings.ts	Added ssrUnsupportedWarning constant used by the new SSR guard in nativeStore.ts.
.changeset/brown-ducks-cross.md	New changeset entry marking this as a patch release for gt-react-native.
