New feature
Enhancement
Refactoring

📜 Description

Exposes the Cocoa SDK's attachAllThreads option (added in v9.9.0) so React Native users can configure it from JS via Sentry.init(). When enabled, full stack traces for all threads are attached to all captured events on iOS.

The option is automatically forwarded to the native iOS SDK via optionsWithDictionary: — no custom native bridge code is needed.

💡 Motivation and Context

Closes#5959

The Cocoa SDK v9.9.0 introduced attachAllThreads (sentry-cocoa#7764). This PR makes it available to RN users.

💚 How did you test it?

Added a test in wrapper.test.ts verifying the option is forwarded to initNativeSdk
All existing tests pass

📝 Checklist

I added tests to verify changes
No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled
I updated the docs if needed.
I updated the wizard if needed.
All tests passing
No breaking changes
