Avoid inlining TypeScript helpers (__rest, __awaiter) in every file of dist/js #6955

Problem Statement

@sentry/react-native@8.26.0 ships TypeScript helpers inlined into its compiled output, so the same helper code is duplicated in every file that uses it. This adds ~7.0 KB of repeated code to the JS bundle of every app using the SDK.

Inlined helpers: __rest, __awaiter

Solution Brainstorm

Enable "importHelpers": true in tsconfig.json and add tslib as a dependency. The compiler will then import the helpers from tslib instead of emitting a copy in each file, so they're included only once in the app bundle (and deduplicated with other packages that already use tslib).

Alternatively, raising the compile target (e.g. ES2018+) would let TypeScript emit native object rest / async-await and drop these helpers entirely, leaving down-levelling to the app's Babel/Metro setup.
