Extract java-kotlin language analysis from the shared CodeQL Advanced
workflow into a dedicated codeql-kotlin.yml workflow. This allows the
Kotlin analysis (which requires Java, Gradle, and a manual build) to
run independently with path filtering on packages/kilo-jetbrains,
reducing unnecessary CI runs for unrelated changes.
- Add new codeql-kotlin.yml with path-scoped triggers
- Remove java-kotlin from the matrix in codeql.yml
- Simplify codeql.yml by removing conditional Java/Gradle setup steps
- Register codeql-kotlin.yml in check-workflows.ts active set
