[Bug]: "shopify app dev" swallows server logs and rebuild output on Ubuntu 24.04 (Hot Reload works, Terminal silent)

[salman-sc]

Issue Description: I am experiencing an issue on Ubuntu 24.04 where shopify app dev runs the app successfully, but swallows all runtime output.

Functionality: Hot-reload is working. If I change a file, the app updates in the browser.

The Problem: The terminal remains completely static. It does not show "rebuilding...", "file changed", or any console.log() output from the backend.

Impact: I cannot debug my app because server-side logs and errors are never printed to the terminal.

This appears to be an issue with how the CLI pipes stdout/stderr from the child process to the main terminal on Ubuntu 24.04. This same project works correctly (showing logs) on Windows.

Environment:

OS: Ubuntu 24.04 LTS

Shopify CLI Version: 3.88.0

Node Version: v20.19.6

Shell: Bash

Steps to Reproduce:

Run shopify app dev.

Wait for the server to start.

Add a console.log("TEST LOG") to a backend loader/action.

Save the file.

Refresh the app in the browser (the change takes effect).

Check the terminal.

Expected Behavior: The terminal should output the "TEST LOG" string and show build status updates.

Actual Behavior: The terminal shows nothing.
