Instrument Android checkout failures

[tiagocandido]

Summary

• Record Android checkout errors, protocol decoding failures, paired navigation retry outcomes, and navigation duration
• Add a default-on telemetry setting with an explicit runtime opt-out that discards buffered measurements
• Lazily and failure-safely initialize telemetry, avoiding threads and wake-ups on the disabled path, and guard recorder creation against a concurrent runtime opt-out
• Report react-native-android as the platform when embedded in React Native, android otherwise
• Keep retry reasons paired across attempts and preserve preload attribution captured at navigation start
• Match the cross-platform decode taxonomy: envelope decode failures record envelope and params decode failures record params
• Document the bounded diagnostic data and explicit opt-out

Validation

• Android unit tests
• Detekt
• Android API dump and API compatibility checks
