In #124 the problem with quitting the terminal is solved.

Nevertheless, it was noticed when developing scraping software with playwright tests that are executed for a long time, the tests that are run are not canceled. This caused that even computer was completely blocked with a couple of runs.

This implementation also handles sigterm properly in headless mode.

How to test this:

Create slow running script test:

 # slow_test.sh
  #!/bin/bash
  echo "test script started, PID=$$"
  sleep 60
  echo "test script completed" >> /tmp/codeplain_test_completed.txt

and chmod +x slow_test.sh

and reference it from config file. Run the rendering and exit when running unit test script (ctrl +d)

On main:
grep -af slow_test should return PID

On this branch:

  pgrep -a sleep         # should return nothing
  pgrep -af slow_test    # should return nothing

Note: When canceling the render, there are other actions that might not be terminated properly - REST API calls, writing files or git commits. But we actually don't care of them as we are restarting only from certain git check points.
