💡 What: Added robust input validation to bitcoin_trading_simulation.py to check for invalid command-line arguments (e.g., negative days, zero cash).
🎯 Why: Previously, running the simulation with negative values (e.g., --days -10) would either produce nonsensical results or crash with a Python traceback. This change ensures the user gets a clear, actionable error message.
📸 Before:

$ python bitcoin_trading_simulation.py --days -10
# (Runs with 0 days or nonsensical output)

📸 After:

$ python bitcoin_trading_simulation.py --days -10
Error: Days must be a positive integer.

Accessibility: Error messages use Colors.FAIL (Red) for visibility, but respect the --no-color flag for users who disable it.

- Validate 'days', 'initial-cash', 'initial-price', and 'volatility' to ensure positive/non-negative values.
- Display user-friendly error messages in red (unless --no-color is used) and exit with code 1 on failure.
- Add 'test_cli_args.py' to verify invalid inputs and error handling.
- Improve UX by preventing simulation crashes with cryptic Python tracebacks.

… workflow

- Add `src/main.rs` to satisfy the Cargo.toml build target.
- Add `target/` to `.gitignore` to prevent build artifacts from polluting the repo.
- Remove `.github/workflows/terraform.yml` as no Terraform configuration exists.
