Integrate Google Play Console data with Sentry

### Problem Statement

Google Play Console surfaces valuable data — crash reports, ANR rates, Android vitals, and issue annotations — that has no connection to Sentry issues. Developers currently have to context-switch between both tools and manually correlate the same crashes.

### Request

* Link Sentry issues to corresponding Google Play Console issues
* Surface Play Console annotations (e.g. ANR annotations, crash rate markers) alongside Sentry issue timelines
* Potentially ingest Play Console crash/ANR data as a signal in Sentry

Action taken on behalf of Michael Chai.

No implementation file, entry point, or test is named. First investigate the Google Play Console APIs and the existing Sentry issue and timeline integration, then clarify whether linking, annotations, ingestion, or all three are in scope; done should be a defined scope with acceptance criteria.
