Problem & expected behavior (under 200 words)

Running a script through tsx and piping its output to an early-closing reader such as head crashes with an unhandled Error: write EPIPE and exit status 1. This makes ordinary shell pipelines fail even though the script itself is valid. The reproduction pins [email protected]; its GitHub Actions workflow runs a plain Node.js control before demonstrating the failing tsx pipeline.

The equivalent loop run with plain Node.js exits quietly with pipeline statuses 0 0. I expect tsx to match that behavior and terminate cleanly when stdout closes early.
