📜 Description

Adds a logsEnabled option to SentryTimberIntegration and SentryTimberTree, defaulting to false while preserving their existing JVM constructor signatures.

Adds SentryAndroidOptions.timberLogsEnabled and the io.sentry.timber.logs.enabled manifest key for auto-installed Timber integrations. Manually installed integrations and trees can opt in through their new constructor arguments.

Timber forwarding requires both this local opt-in and the existing aggregate core Logs flag until that flag is removed later in the stack. Event and breadcrumb capture remain unchanged.

💡 Motivation and Context

Logging integrations need explicit local opt-ins before the aggregate core Logs flag can be removed. This keeps automatic Timber log forwarding disabled by default while allowing applications to opt in through Java, Kotlin, or Android manifest configuration.

💚 How did you test it?

• ./gradlew spotlessApply apiDump
• ./gradlew :sentry-android-timber:testReleaseUnitTest :sentry-android-core:testReleaseUnitTest
• Added tests for default-disabled and explicit opt-in behavior for auto-installed and manual Timber integrations and trees
• Added regression coverage for independent event and breadcrumb capture

📝 Checklist

• I added GH Issue ID & Linear ID
• I added tests to verify the 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.
• Review from the native team if needed.
• No breaking change or entry added to the changelog.
• No breaking change for hybrid SDKs or communicated to hybrid SDKs.

🔮 Next steps

Add the Logcat Logs opt-in before removing the aggregate core Logs flag.
