I think we need some bigger changes before this can be merged, looking at the changelog + CI failure

@cursor fix this PR using the https://github.com/Kotlin/kotlin-agent-skills/blob/main/skills/kotlin-tooling-agp9-migration/SKILL.md skill.

[cursor]

Applied the Kotlin AGP 9 migration skill (Path A) to fix the CI failure caused by com.android.library conflicting with kotlin.multiplatform on AGP 9.

Root cause

AGP 9 registers a built-in kotlin extension when com.android.library is applied, which collides with the KMP plugin (Cannot add extension with name 'kotlin').

Changes made

1. gradle/libs.versions.toml — Swapped com.android.library for com.android.kotlin.multiplatform.library (v9.2.0).

2. coroutines/build.gradle.kts and temporal/build.gradle.kts — Path A migration:

   • Plugin: com.android.kotlin.multiplatform.library
   • Config moved from android {} into kotlin { android {} }
   • Removed publishLibraryVariants("debug", "release") (single-variant in AGP 9)
   • Enabled androidResources (coroutines has AndroidManifest.xml)
   • Enabled withHostTest {} for test source sets

3. temporal/src/androidUnitTest → androidHostTest — Required for the new host-test source set naming.

4. gradle.properties — Removed deprecated android.defaults.buildfeatures.* properties (removed in AGP 9).

Verification

Locally ran the CI-equivalent commands successfully:

• ./gradlew assemble
• ./gradlew check
• ./gradlew publishToMavenLocal

Changes are committed and pushed to renovate/com.android.library-9.x (commit 558587c). CI should pass on the next run.
