fix(android): Remove AndroidRuntimeManager to prevent ANRs during SDK init (#5127)

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

StrictMode.setVmPolicy()/setThreadPolicy() calls inside
runWithRelaxedPolicy() triggered binder IPC on the main thread, causing
ANRs (SDK-CRASHES-JAVA-32FQ 34k+, SDK-CRASHES-JAVA-32PH 21k+,
SDK-CRASHES-JAVA-32Q9 18k+ events). StrictMode only logs warnings in
production by default, so relaxing it is unnecessary and harmful.

* changelog: Add entry for AndroidRuntimeManager removal

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix(test): Remove initNotThrowStrictMode test

This test validated that StrictMode with penaltyDeath() didn't crash
during SDK init. Since we removed the RuntimeManager that relaxed
StrictMode, this test is no longer applicable — the SDK no longer
attempts to suppress StrictMode violations.

 ### Fixes
 
+- Remove `AndroidRuntimeManager` StrictMode relaxation to prevent ANRs during SDK init ([#5127](https://github.com/getsentry/sentry-java/pull/5127))
 - Fix crash when unregistering `SystemEventsBroadcastReceiver` with try-catch block. ([#5106](https://github.com/getsentry/sentry-java/pull/5106))
 - Log an actionable error message when Relay returns HTTP 413 (Content Too Large) ([#5115](https://github.com/getsentry/sentry-java/pull/5115))
   - Also switch the client report discard reason for all HTTP 4xx/5xx errors (except 429) from `network_error` to `send_error`
