Fix command listing to show only main commands, hiding singular aliases

[oalami]

This PR implements a custom Click group class to manage command aliases, ensuring only main commands appear in help output while keeping singular forms accessible as hidden aliases. The solution centralizes alias management through a new AliasedGroup class that maps aliases to their main commands internally.

Key changes:

Introduced AliasedGroup class with internal alias mapping and resolution
Replaced duplicate command registrations with add_command_with_alias() calls
Converted all plural-singular command pairs to use hidden aliases
