📜 Description

Adds screenshot options to control masking of sensitive content in error screenshots on both Android and iOS.

Sentry.init({
  dsn: '...',
  attachScreenshot: true,
  screenshot: {
    maskAllText: true,        // default: true
    maskAllImages: true,       // default: true
    maskedViewClasses: ['com.mapbox.maps.MapView'],  // native class names
    unmaskedViewClasses: ['com.example.SafeView'],
  },
});

Options:

• maskAllText / maskAllImages — toggle automatic masking of text and images (default: true)
• maskedViewClasses / unmaskedViewClasses — mask or unmask specific native view classes (useful for third-party libraries like map SDKs, payment forms, video players)

Platform support:

• Android: Bridges to SentryScreenshotOptions via options.getScreenshot() (available since sentry-android 8.34.0, current: 8.38.0)
• iOS: Bridges to SentryViewScreenshotOptions via init(dictionary:) (Cocoa SDK 9.10.0)

💡 Motivation and Context

Both native SDKs support screenshot masking for error screenshots, but the React Native SDK only exposed attachScreenshot as a boolean with no way to configure masking. This meant error screenshots could contain sensitive data (text, images) with no opt-out.

Closes #5763

💚 How did you test it?

• Added unit test in wrapper.test.ts verifying screenshot options pass through to the native module
• Added iOS native tests in RNSentryStartTests.swift for screenshot masking options and defaults
• TypeScript compiles successfully (yarn build)
• All existing tests pass (yarn test)
• Added usage to the React Native sample app

📝 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. (docs(react-native): Document screenshot masking options sentry-docs#17362)
• I updated the wizard if needed.
• All tests passing
• No breaking changes
