prober: AGP 9.2 / Gradle 9.6 / Kotlin 2.2.10, targetSdk 36, build 5

Lifts the build off the JDK-21 ceiling — the old AGP 8.7.3 pin could not run
on JDK 25. Two AGP-9 migration edits were required:

- AGP 9 ships built-in Kotlin support, so applying org.jetbrains.kotlin.android
  alongside it fails with "extension with name kotlin already registered";
  the alias is dropped (kotlin.compose / kotlin.serialization stay, they are
  separate compiler plugins).
- kotlinOptions { jvmTarget } came from that plugin and no longer resolves;
  AGP derives jvmTarget from compileOptions instead.

compileSdk/targetSdk 35 -> 36, since Android Studio ships API 36.1 by default
and installing 35 was avoidable churn. versionCode 5 so the reports from this
toolchain are attributable (build 4 was already archived from the old one).

Also fixes a missing comma that left .claude/settings.json invalid JSON.
