Greptile Summary

This PR improves AdMob consent handling, privacy-choice feedback, and banner recovery behavior while coordinating interstitial loading with extension installation.

• Deduplicates concurrent privacy-option requests and safely handles unavailable native privacy UI.
• Adds banner load listeners, bounded retry behavior, and lifecycle cleanup.
• Loads interstitial ads alongside extension installation and displays them after completion.
• Adds focused tests for consent concurrency and banner retry/state transitions.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.
