+ * Updates src/languages/builtin.json by querying the CodeQL CLI for:
+ * - Languages that have default queries (via codeql-extractor.yml)
+ * - Language aliases (via `codeql resolve languages --format=betterjson --extractor-include-aliases`)
+ *
+ * Usage:
+ *   npx tsx pr-checks/update-builtin-languages.ts [path-to-codeql]
+ *
+ * If no path is given, falls back to "codeql".
