tty in node in local_resource kills tilt

[nicks]

Related to https://github.com/tilt-dev/tilt/issues/6378, but the repro steps are slightly different :thinking:

Steps to Reproduce

Tiltfile:

local_resource(
    'test',
    ['node', './main.js'],
    stdin_mode='pty')

main.js:

const { spawn } = require('node:child_process');

let promise = new Promise((resolve, reject) => {
  let proc = spawn('/bin/zsh', [
    '-i',
    '-l',
    '-c',
    'echo exit',
  ]);

  proc.on('error', (err) => {
    console.log('ERROR PROCESS');
  });

  proc.on('close', (code, signal) => {
    console.log('CLOSE PROCESS');
  });
});

1) Run tilt up and wait a little while 2) Hit space

Expected Behavior

Tilt should successfully run the command

Current Behavior

On macOS, tilt crashes with suspended (tty input) On Linux, the terminal gets mysteriously detached from the tilt process
