chore: update launchdarkly-android-client-sdk to 5.14.0 and appcompat to 1.8.0

[devin-ai-integration]

Summary

Routine dependency refresh for this example. All three are exact pins, so they only move when bumped:

• com.launchdarkly:launchdarkly-android-client-sdk 5.13.3 → 5.14.0 (latest on Maven Central, same major).
• androidx.appcompat:appcompat 1.7.1 → 1.8.0 (latest release; builds fine against the example's existing compileSdk 34).
• Gradle wrapper 8.14.3 → 8.14.5 (latest 8.x). AGP (8.13.2) is already latest, so it is untouched.

No example source changes: the app's SDK usage (LDConfig.Builder(AutoEnvAttributes.Enabled), LDClient.init(app, config, context, 5), boolVariation, registerFeatureFlagListener, flush) is all current in 5.14.0, and a --warning-mode all build reports zero deprecation warnings.

Validated end-to-end on an Android 34 x86_64 emulator with the real hello-apps mobile key and flag key supplied via untracked local edits (never committed):

Implementation details

• ./gradlew assembleDebug --warning-mode all with JDK 17 and Android SDK/build-tools 34 — BUILD SUCCESSFUL, no deprecation or other warnings.
• androidx.appcompat:appcompat:1.8.0 resolves cleanly and does not raise the AAR-metadata minCompileSdk requirement above 34, so no compileSdk/targetSdk change is needed. The SDK's own transitive appcompat:1.1.0 is upgraded to 1.8.0 by this pin.
• adb install + am start, then uiautomator dump, printed Feature flag 'hello-boolean' is true — the same assertion the repo's run.yml workflow makes.
• No documented minimums were raised: the README does not pin dependency versions, and minSdkVersion 24 / compileSdk 34 are unchanged since nothing requires more.

Limitations

Verified on an emulator only, not a physical device.

Note

Overview
This PR is a dependency-only refresh for the hello-android-java example—no application source or SDK configuration changes.

app/build.gradle pins androidx.appcompat:appcompat from 1.7.1 → 1.8.0 and com.launchdarkly:launchdarkly-android-client-sdk from 5.13.3 → 5.14.0 (same major for the SDK). gradle/wrapper/gradle-wrapper.properties updates the wrapper from Gradle 8.14.3 → 8.14.5. compileSdk 34, minSdkVersion 24, and Java 17 settings are unchanged.
