datasetviewer bundles third-party JavaScript, compiled from srcjs/ into
inst/htmlwidgets/datasetviewer.js by esbuild (see tools/build.R). The DuckDB
runtime engine is not committed or shipped in the package tarball; it is the
JavaScript API of @duckdb/duckdb-wasm that is bundled, while the WebAssembly
binaries are fetched at install time or loaded from a CDN at runtime (see
R/duckdb.R and tools/fetch-duckdb.R).
