• chore(deps): bump ktorClient from 3.0.0 to 3.6.1 #6478
• fix(ktor): [Ktor 3.6 2] Preserve Ktor 3.0 runtime compatibility #6517
• test(ktor): [Ktor 3.6 3] Add Ktor 3.0 compatibility suite #6520

📜 Description

Construct the Ktor client plugin's attribute keys with explicit TypeInfo values instead of using Ktor's inline AttributeKey factory.

💡 Motivation and Context

When compiled against Ktor 3.6.1, the inline factory embeds a call to a new three-argument TypeInfo constructor. Running those compiled SDK classes with older Ktor 3.x versions then fails with NoSuchMethodError.

The explicit construction uses the stable two-argument TypeInfo constructor and preserves runtime compatibility with Ktor 3.0.0 through 3.6.1.

💚 How did you test it?

• Ran ./gradlew spotlessApply updateKotlinAbi
• Ran all 32 SentryKtorClientPluginTest tests after compiling once against Ktor 3.6.1 and replacing only the Ktor runtime dependencies with 3.0.0, 3.1.3, 3.2.3, 3.3.3, 3.4.3, 3.5.1, and 3.6.1; all passed
• Ran ./gradlew :sentry-ktor-client:checkKotlinAbi
• Verified with javap that the compiled plugin calls TypeInfo(KClass, KType) and does not reference TypeInfo(KClass, boolean, KType)

Test suite misses production classes

High Severity

The testKtor300 suite never depends on project(), so main output can be missing from the Test runtime classpath. Extra JVM test suites do not inherit production classes the way built-in test does, and associateWith only friends the Kotlin compilation. Without the plugin jar on that classpath, the suite cannot load SentryKtorClientPlugin and does not verify Ktor 3.0.0 runtime compatibility.
