codeql.yml

# CodeQL static analysis: the Java app AND the JNI/C glue. Mirrors the httrack
# repo's codeql.yml (security-extended). c-cpp is scoped to htslibjni*.c via
# .github/codeql/codeql-config.yml so the vendored engine isn't double-scanned.
#
# java-kotlin uses build-mode: none (the app doesn't build under modern Gradle
# until the AGP 8 migration in Phase 3 — no build needed to analyze the source).
# c-cpp builds the JNI glue via a self-contained NDK setup (no pre-published image).
