Version Catalog Support

Im using gradle 8.2 with version catalog like this:
```
plugins {
alias(libs.plugins.kotlin)
}
```

Im getting this error in my build.gradle.kts
```
val Project.libs: LibrariesForLibs' can't be called in this context by implicit receiver. Use the explicit one if necessary kotlin (DSL_SCOPE_VIOLATION)
Cannot access class 'org.gradle.accessors.dm.LibrariesForLibs'. Check your module classpath for missing or conflicting dependencies kotlin (MISSING_DEPENDENCY_CLASS)
```

Start by reproducing the reported diagnostics in a Gradle 8.2 project using the shown build.gradle.kts version-catalog snippet. Trace how the language server handles Kotlin DSL generated accessors and define completion when the snippet no longer reports DSL_SCOPE_VIOLATION or MISSING_DEPENDENCY_CLASS.
