Update LaunchDarkly Android Client SDK to 5.11.0

[devin-ai-integration]

Summary

Bumps launchdarkly-android-client-sdk from 4.2.2 to 5.11.0 — a major version upgrade (4.x → 5.x).

SDK 5.11.0 requires newer build tooling than what the project previously used (AGP 4.1.3 / Gradle 6.7). The build configuration has been modernized to match.

Updates since last revision

Upgraded the entire build toolchain for SDK 5.11.0 compatibility:

Component	Before	After
AGP	4.1.3	8.7.0
Gradle wrapper	6.7	8.9
compileSdk / targetSdk	33	34
minSdk	21	24

Additional structural changes:

• Migrated build.gradle from legacy buildscript/allprojects DSL to modern plugins DSL
• Added pluginManagement and dependencyResolutionManagement blocks to settings.gradle
• Moved namespace from AndroidManifest.xml package attribute to app/build.gradle (required by AGP 8.x)

Review & Testing Checklist for Human

• Verify minSdk 24 is actually required. This was bumped from 21 — confirm whether SDK 5.x truly requires API 24+. If not, revert to 21 to avoid dropping Android 5.0–6.x device support unnecessarily.
• Verify API compatibility across the v4 → v5 boundary. The app code uses LDClient, LDConfig.Builder, LDContext, ContextKind, and LaunchDarklyException. Confirm none of these were removed or had breaking signature changes in v5. Check the SDK changelog / migration guide for breaking changes.
• Build the project in Android Studio and confirm it compiles without errors. The build.gradle and settings.gradle were substantially rewritten (legacy → modern DSL migration), so verify Gradle sync and build succeed.
• Run the app on an emulator or device with a valid mobile key and confirm flag evaluation works end-to-end.
• Check that LaunchDarklyException (used in MainActivity.java catch block) still exists and is thrown in the same circumstances in v5.

Notes

• No CI exists on this repo — there is zero automated build validation. All verification must be done manually.
• This change was not tested locally — no Android build toolchain was available in the build environment. Human verification is required.
• This is a major version bump plus a significant build tooling overhaul; CI alone would be insufficient even if it existed.
