Function handle_smart_init_with 

pub fn handle_smart_init_with<R: ConfigEnvironment>(
    template_arg: Option<&str>,
    force: bool,
    colors: Colors,
    env: &R,
) -> Result<bool>

Handle the smart --init flag with a custom path resolver.

This function intelligently determines what the user wants to initialize:

• If a value is provided and matches a known template name → create PROMPT.md
• If config doesn’t exist and no template specified → create config
• If config exists but PROMPT.md doesn’t → prompt to create PROMPT.md
• If both exist → show helpful message about what’s already set up

Arguments

• template_arg - Optional template name from --init=TEMPLATE
• force - If true, overwrite existing PROMPT.md without prompting
• colors - Terminal color configuration for output
• resolver - Path resolver for determining config file locations

Returns

Returns Ok(true) if the flag was handled (program should exit after), or Ok(false) if not handled, or an error if initialization failed.
