PR Stack (ANR Flame Graph)

• feat(anr): Add flame graph attachment helper for ANR profiles #6596
• feat(anr): Send ANR profiles as flame graph attachments instead of profile chunks #6597

---

📜 Description

Adds AnrFlameGraphAttachment.fromAnrProfile(AnrProfile, proguardUuid), which turns an ANR profile into a flame graph attachment (flamegraph.json, event.flamegraph). The payload is modeled by new AnrFlameGraph / AnrFlameGraphNode / AnrFlameGraphTree protocol classes. debug_meta holds only the ProGuard image, since only the JVM main thread is sampled.

The helper is not wired up yet; the ANR profile chunk is unchanged.

💡 Motivation and Context

Lets ANR events carry an aggregated call tree of the main thread alongside the existing profile chunk.

💚 How did you test it?

Unit tests.

📝 Checklist

• I added tests to verify the changes.
• No new PII added or SDK only sends newly added PII if sendDefaultPII is enabled.
• No breaking change or entry added to the changelog.

🔮 Next steps

Attach the flame graph to ANR events in ApplicationExitInfoEventProcessor (#6597).
