chore: bump version to 0.2.0

[jvsena42]

Summary

Version bump for the v0.2.0 release, raising both platforms together.

This is the first release where Android and iOS versions agree: iOS was still on the Xcode template defaults (MARKETING_VERSION=1.0, CURRENT_PROJECT_VERSION=1) while Android was on 0.1.0/1. Going forward the /release skill keeps CURRENT_PROJECT_VERSION equal to the Android versionCode.

Changes

• composeApp/build.gradle.kts: versionCode 1 → 2, versionName 0.1.0 → 0.2.0
• iosApp/Configuration/Config.xcconfig: CURRENT_PROJECT_VERSION 1 → 2, MARKETING_VERSION 1.0 → 0.2.0

Test plan

• ./gradlew detekt passes.
• ./gradlew :shared:allTests passes.
• After merge, ./gradlew clean :composeApp:assembleRelease produces an APK that apksigner verify accepts, with the manifest reporting versionCode='2' versionName='0.2.0'.
• Config.xcconfig is the base configuration for both project-level build configs, so the bump reaches the iosApp and WornShareExtension targets; the Info.plists carry no version keys.
• Diff contains only the four version lines — TEAM_ID is untouched and still empty.

Checklist

• ./gradlew detekt passes
• Tested on Android
• Tested on iOS
• Updated documentation (if applicable)
