chore: update launchdarkly-android-client-sdk to 5.15.0

[devin-ai-integration]

Summary

Bumps the Android client SDK to the latest 5.x release; no source changes were needed.

• com.launchdarkly:launchdarkly-android-client-sdk 5.14.0 → 5.15.0 (exact pin preserved).
• No other dependency/tooling change: androidx.appcompat 1.8.0, AGP 8.13.2 and Gradle 8.14.5 are already the latest within their current majors.
• No deprecated SDK APIs in the example — it already uses the LDClient.init(app, config, context, timeout) variant (the no-timeout init overload is the deprecated one).

Implementation details

Verification: built assembleDebug and ran the app on a local API 34 x86_64 emulator with the hello-apps mobile key and flag key patched in locally (never committed). The app rendered Feature flag 'hello-boolean' is true; logcat showed no SDK deprecation or error output.

Version check: maven-metadata.xml for the SDK lists 5.15.0 as latest (no 6.x), Google's Maven lists appcompat 1.8.0 as latest stable and AGP 8.13.2 as latest 8.x. Gradle wrapper left at 8.14.5 to stay within the current major. README mentions no version numbers, so no docs change.

Note

Overview
