// One build pass for the whole package. Everything is bundled on the neutral
// platform so the output carries no Node assumptions and runs unchanged in Node,
// edge runtimes, and the browser; the only Node-touching code (the node entry and
// the CLI) imports node: built-ins, which stay external on any platform. The CLI
// entry begins with a shebang in its source, which tsup preserves and marks
// executable, so no per-entry banner is needed and a single config can clean the
// output folder once without racing a second pass.
