fix: custom config path

[justinmchase]

Proposed changes

For some reason the -c,--config options are not working as expected.

All of the other options when you map them with an alias such as -n,--name when the are passed to the command function they are on the fullname property of the arguments such as { name }.

Config appears to be an exception to the rule and is always applied as { c } for an unknown reason.

This change models the c?: string field on the args and then normalizes it where it is used

psuedo-logic

// old
const configPath = config;

// new
const configPath = config ?? c;

Pull Request Overview

This PR fixes an issue where the -c/--config command-line options were not working correctly due to the argument being passed as c instead of config in the context object. The fix adds support for both the short form (c) and long form (config) to ensure the custom config path option works as expected.

• Adds fallback logic to use c when config is not provided
• Updates the IContext interface to include the c property
• Adds comprehensive test coverage for the custom config functionality
