feat: Add availability.exit_on_skipped

[shivaraj-bh]

resolves #225

Here’s a simple process-compose configuration to try this feature:

processes:
  process1:
    command: "echo 'Hi from Process1'"
    depends_on:
      process2:
        condition: process_completed_successfully
    availability:
      exit_on_skipped: true
  process2:
    command: "echo 'Hi from Process2'; exit 1"
  process3:
    command: "while true; do echo 'Running...'; sleep 1; done"
