fix(android): Remove AndroidRuntimeManager to prevent ANRs during SDK init

[romtsn]

📜 Description

Removes AndroidRuntimeManager, IRuntimeManager, and NeutralRuntimeManager entirely. All operations previously wrapped in runWithRelaxedPolicy() are now called directly (inlined).

Also removes the runtimeManager field, getter, and setter from SentryOptions.

💡 Motivation and Context

AndroidRuntimeManager.runWithRelaxedPolicy() temporarily disables Android's StrictMode policies around disk I/O during SDK init. However, the StrictMode.setVmPolicy() / StrictMode.setThreadPolicy() calls themselves trigger binder IPC under the hood, causing ANRs on the main thread.

Sentry evidence: 3 major ANR issues across versions 8.24.0–8.32.0, affecting devices on Android 11–16:

• SDK-CRASHES-JAVA-32FQ — 34k+ events
• SDK-CRASHES-JAVA-32PH — 21k+ events
• SDK-CRASHES-JAVA-32Q9 — 18k+ events

All stack traces point to runWithRelaxedPolicy() during SentryAndroid.init().

Why removal is safe: StrictMode only logs warnings in production by default. Apps that configure StrictMode with penaltyDeath() do so consciously and accept the consequences. ANRs are far worse than StrictMode violations.

• fixes: Multiple ANRs on Init after upgrading from 8.18.0 to 8.25.0 #4960

💚 How did you test it?

• ./gradlew :sentry:test — passes
• ./gradlew :sentry-android-core:testDebugUnitTest — passes
• ./gradlew spotlessApply apiDump — formatting and API dump regenerated
• rg "IRuntimeManager|RuntimeManager|runWithRelaxedPolicy|runtimeManager" — returns no matches in source

📝 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

Monitor SDK crash dashboards to confirm the 3 ANR issues (SDK-CRASHES-JAVA-32FQ, SDK-CRASHES-JAVA-32PH, SDK-CRASHES-JAVA-32Q9) stop appearing in new versions.
