Build modernization: Gradle 9.5, AGP 9.2, Kotlin 2.3, and tooling updates

[solcott]

Overview

This PR modernizes the build infrastructure across the board — toolchain upgrades,
configuration cache adoption, CI improvements, and migration to current plugin APIs.

Changes

Gradle & Toolchain

• Gradle 8.6 → 9.5.1
• Added gradle/gradle-daemon-jvm.properties pinning the daemon to Azul JDK 17
• Enabled Gradle configuration cache (org.gradle.configuration-cache=true)
• Disabled configureondemand (incompatible with configuration cache)
• Added updateDaemonJvm task configured for JDK 17 / Azul

Dependency & Plugin Updates

• AGP 8.0 → 9.2.1 (migrates to com.android.kotlin.multiplatform.library plugin)
• Kotlin 2.0.20 → 2.3.21
• kotlinx.coroutines 1.8.1 → 1.11.0
• kotlinx.serialization 1.6.3 → 1.11.0
• atomicfu 0.24.0 → 0.33.0
• Dokka 1.9.20 → 2.2.0 (new DokkaExtension API)
• KMMBridge 0.3.2 → 1.2.1 (migrates to co.touchlab.kmmbridge.github plugin)
• ktlint Gradle plugin 12.1 → 14.2, ktlint 0.39 → 1.8
• Kover 0.9.0-RC → 0.9.8
• Binary compatibility validator 0.15.0-Beta.2 → 0.18.1
• vanniktech maven publish 0.34 → 0.36
• Removed unused dependencies: molecule, androidx-paging, jacoco

Build Script Modernization

• Removed buildscript {} block — all plugins now declared via alias(libs.plugins.*) in the root build.gradle.kts
• All plugin versions centralized in libs.versions.toml
• Added VersionCatalogExt.kt with typed accessors for version catalog values (JVM toolchain, compat version, SDK levels, store version), replacing the hardcoded Versions object
• JVM target/toolchain versions now driven from the version catalog (jvmToolchain = 17, jvmCompat = 11)
• configureAndroid() updated for the new multiplatform Android library plugin API (namespace, withHostTest/withDeviceTest, compiler options)
• Removed per-module android { namespace = ... } and AndroidManifest.xml from cache, core, and multicast — namespace now set centrally in the convention plugin
• Migrated sourceSets { val x by getting { } } to sourceSets { x { } } idiom across submodules

CI / GitHub Actions

• actions/checkout v4 → v6
• actions/setup-java v4 → v5
• gradle/gradle-build-action → gradle/actions/setup-gradle@v6
• codecov/codecov-action v4 → v6
• Added explicit permissions block to CI job (least-privilege: contents: read, checks: write, pull-requests: write)
• Added --continue flag to build step so all module failures are reported in one run
• Added JUnit test report publishing via mikepenz/action-junit-report@v5 (runs on failure too)
• Codecov upload now guarded by github.repository == 'MobileNativeFoundation/Store' to avoid failures on forks
• Overhauled create_swift_package.yml / KMMBridge workflows based on current KMMBridgeSPMQuickStart template; added separate KMMBridge-Debug.yml and KMMBridge-Release.yml dispatch workflows

Lint / Style

• Added .editorconfig disabling ktlint_standard_import-ordering for Kotlin files
• Expanded ktlint additionalEditorconfig rules to suppress several noisy checks project-wide

Other

• rx2: migrated deprecated TestCoroutineScope → TestScope
• cache API: relaxed getAllPresent() from abstract to default interface method
• gradle.properties: removed deprecated kotlin.js.compiler=ir
• VERSION_NAME set to 5.1.0-SNAPSHOT for development

[solcott]

Looks like the following github actions are not on your orgs allow list:

softprops/action-gh-release@v2 — used in create_swift_package.yml. Used for KMMBridge publishing.
touchlab/ga-update-release-tag@v1 — used in create_swift_package.yml. Used for KMMBridge publishing.

It looks like the Create Swift Package action has never been run. If you don't think it will be run in the future I can remove the KMMBridge support as well as create_swift_package.yml where these actions are used.
