3.6.0 reports all JS dependencies as unused in KMP project with JS target

**Plugin version**
3.6.0 / 3.6.1

**Gradle version**
9.4.1

**JDK version**
25

**(Optional) Kotlin and Kotlin Gradle Plugin (KGP) version**
2.1.20

**Describe the bug**
I wanted to update DAGP from 3.5.1 to 3.6.1 but then got a complaint about unused dependencies for all my JS-target dependencies.

**Expected behavior**
Not failing.
If JS target is not supported, it should be ignored.
If it is supported, it should work.

Reproduce the report with dependency-analysis-gradle-plugin 3.6.0 or 3.6.1, Gradle 9.4.1, JDK 25, and Kotlin/KGP 2.1.20 in a Kotlin Multiplatform project with a JS target. Compare the generated unused-dependency advice for JS-target dependencies; done means supported JS dependencies are handled correctly or the JS target is explicitly ignored without failing.
