1/// Handle the smart `--init` flag with a custom path resolver.
2///
3/// This function intelligently determines what the user wants to initialize:
4/// - If a value is provided and matches a known template name -> create PROMPT.md
5/// - If config doesn't exist and no template specified -> create config
6/// - If config exists but PROMPT.md doesn't -> prompt to create PROMPT.md
7/// - If both exist -> show helpful message about what's already set up
8///
9/// # Arguments
10///
11/// * `template_arg` - Optional template name from `--init=TEMPLATE`
12/// * `force` - If true, overwrite existing PROMPT.md without prompting
13/// * `colors` - Terminal color configuration for output
14/// * `env` - Path resolver for determining config file locations
15///
16/// # Returns
17///
18/// Returns `Ok(true)` if the flag was handled (program should exit after),
19/// or `Ok(false)` if not handled, or an error if initialization failed.
