[1/4] chore(build): Bump Kotlin to 2.2.21 and Gradle to 8.13 to unblock spm4Kmp

[buenaflor]

First step of migrating the SDK's internal Apple build from the Kotlin CocoaPods plugin to spm4Kmp. This PR contains only the toolchain/build upgrade required to unblock that migration — no behavioral or public API change.

Why

Both spm4Kmp and the installed Xcode 26 require Kotlin 2.2.20+/Gradle 8.12+. Kotlin 2.2.21 is the first version whose cinterop commonizer handles the Xcode 26 Metal SDK headers (2.2.20 crashes with Unresolved classifier: platform/Metal/...). Landing this independently keeps the riskier spm4Kmp swap (the next PR in the stack) small and reviewable.

What

• Bump Kotlin 2.2.21, Gradle 8.13, AGP 8.7.3, compileSdk 35; plugin bumps (vanniktech-publish 0.30.0, kover 0.9.1, detekt 1.23.8, dokka 1.9.20, buildkonfig 0.17.1, spotless 7.0.2), serialization 1.7.3, coroutines 1.9.0, Compose 1.9.0.
• Migrate vanniktech publish DSL (RELEASE_SIGNING_ENABLED Gradle property), kover 0.9 DSL, AGP 8 namespace (strip package from manifests), and kotlinOptions → compilerOptions.
• Re-enable buildFeatures { buildConfig = true } to preserve the Android public API.
• Fix no-op stub target (js/wasmJs/linux/mingw) test wiring under Kotlin 2.2.x's shared web source set.
• ktlint 1.x reformat via spotlessApply (+ .editorconfig) and regenerated detekt baseline — this accounts for most of the diff.
• Remove the unused compose.version Gradle property and add a changelog entry for the toolchain bump.

Verification

• CI runs the full pipeline on this PR (Lib + Plugin workflows, Danger, CodeQL, semgrep).
• Locally verified on the upgraded toolchain: :sentry-kotlin-multiplatform:build (all targets + tests), gradle-plugin tests, apiCheck, detekt, and the Apple samples (incl. CocoaPods xcodebuild).

Part 1/4 of the spm4Kmp migration stack: #556 → #557 → #560 → #559.

Pull request overview

This PR upgrades the repository’s build/toolchain baseline (Kotlin/Gradle/AGP and related plugins) as a prerequisite for the upcoming internal Apple build migration to spm4Kmp. The changes are primarily build configuration updates plus mechanical formatting/baseline regeneration, with a small amount of test/build wiring adjustment to keep CI/builds working on Kotlin 2.2.x.

Changes:

• Bump toolchain and build plugins (notably Kotlin 2.2.21, Gradle 8.13, AGP 8.x), including required Android namespace migrations and BuildConfig generation re-enable for the Android library.
• Update build logic for newer plugin DSLs (Kotlin compilerOptions, detekt config setter, vanniktech publish signing via property) and add ktlint 1.x formatting pinning via .editorconfig + Spotless overrides.
• Fix Kotlin 2.2.x KMP stub-target test wiring by excluding Ktor from stub test classpaths and disabling stub-target test tasks.
