12/// Handle --dry-run command.
13///
14/// Validates the setup without running any agents:
15/// - Checks PROMPT.md exists and has required sections
16/// - Validates agent configuration
17/// - Reports detected project stack
18/// - Shows checkpoint status if available
19///
20/// # Arguments
21///
22/// * `logger` - Logger for status output
23/// * `_colors` - Color configuration (unused but kept for API consistency)
24/// * `config` - The current Ralph configuration
25/// * `developer_agent` - Name of the developer agent
26/// * `reviewer_agent` - Name of the reviewer agent
27/// * `repo_root` - Path to the repository root
28///
29/// # Returns
30///
31/// Returns `Ok(())` if validation passes, or an error if PROMPT.md validation fails.
