Add GitHub Action to run Kreatures program with automated inputs

[Copilot]

Resolves #[issue_number] by adding a GitHub Action workflow that demonstrates the Kreatures program running exactly as a user would experience it, with all interactive prompts handled automatically.

What this adds

The new workflow .github/workflows/run-program.yml creates a complete demonstration of the Kreatures simulation game that:

• Runs the program end-to-end with a creature named "GitHubRunner"
• Handles all user input prompts automatically using the expect automation tool:
  • Creature naming prompt at startup
  • Child continuation prompts if the creature dies but has offspring
  • Child selection prompts when multiple children exist
  • Final continue prompt at simulation end
• Provides informative output explaining what Kreatures is and what the simulation demonstrates
• Shows complete results including creature behavior, statistics, and final summary

Technical implementation

The workflow uses Ubuntu's expect package to automate interactive input, creating a robust automation script that:

• Sets appropriate timeouts for the simulation
• Handles multiple possible program flows (creature death, reproduction, survival)
• Provides clear error handling and logging
• Demonstrates all core game mechanics (fighting, befriending, reproduction)

When it runs

• On push or pull request to main/master branches
• Can be manually triggered via GitHub's workflow dispatch feature

Example output

The action produces output like this, showing the full creature simulation:

🧬 Starting Kreatures Simulation Demo
======================================

Kreatures is a virtual creature simulation game where:
• You create a creature and release it into an environment
• Your creature interacts with other creatures through fighting, befriending, and reproduction

🎮 Running simulation...
=======================
GitHubRunner was created.
GitHubRunner made friends with Gary!
GitHubRunner made a baby with Billy!
GitHubRunner fought and ate Eric!
[... full simulation output ...]

=== Stats ===
Friendships forged: 8
Babies made: 3
Creatures Eaten: 2

✅ Kreatures simulation completed successfully!

This provides an excellent way for anyone visiting the repository to see the program in action without needing to set up a local environment or manually provide inputs.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
