Upgrade to AGP 9

[priettt]

Goal

Upgrade Android Gradle Plugin from 8.13.2 to 9.0.0.

Changes

• Bump AGP version to 9.0.0
• Bump androidx-benchmark to 1.5.0-alpha01 for AGP 9 compatibility
• Rename plugins in libs.versions.toml (androidLibrary → android-kotlin-multiplatform-library, kotlinMultiplatform → kotlin-multiplatform)
• Extract Android target configuration to KotlinAndroidTargetConfig.kt
• Restructure BuildPlugin to keep common multiplatform config separate from android-specific config
• Fix BuildPlugin to ensure configurePublishing() runs for all modules (fixes compat-bom publishing)
• Fix compat-bom to properly import OpenTelemetry Java BOM version constraints
• Restore kotlin.android plugin in telescope-app example

Looks mostly good. One question about withPlugin and also the CI is failing when building the telescope app.

[fractalwrench]

This looks kind of strange. Do both plugins get applied always? Is it necessary to nest the withPlugin calls or would it function the same outside of this lambda?

[priettt]

I did this so I could access the new KotlinMultiplatformAndroidLibraryTarget, but I think it's an oversight. Some modules might not apply that plugin, and hence they won't be published. That's why CI isn't passing I believe.

I'll rethink this!
