CLI: Align alias listing with docker, Apple and other CLIs

[David Bennett (dkbennett)]

Summary of the Pull Request

Improves WSLC command help by displaying every registered invocation of a command as a fully qualified alias, including equivalent commands exposed at the root. This aligns with docker. If the list is longer than console width it wraps at the alias boundary and keeps at same indentation.

Example docker alias listing:

Example wslc alias listing with this change:

Note that the difference in ordering is due to docker treating "image ls" as the canonical and "image list" as the alias, while wslc treats "image list" as the canonical and "image ls" as the alias. This is the way the command is defined and not a result of the alias listing being incorrect. The canonical is listed first always in the alias list.

The conventional order for alias lists is:

1. Canonical grouped command.
2. Grouped aliases in declared order.
3. Root-level shortcut or alias.

If there is only one command and no aliases nothing is printed at all (and the same is true for wslc).

Detailed Description of the Pull Request / Additional comments

Alias lists now:

• Use the executable name derived from argv[0].
• Include grouped, root-level, and existing command aliases.
• Handle root-specific names such as wslc images.
• Wrap at the console width only between complete aliases.
• Remain unwrapped when output is redirected.

Added tests for aliases.

Validation Steps Performed

Pull request overview

This PR updates WSLC CLI help output so the Aliases section lists each command’s aliases as fully-qualified invocations (including equivalent root-level forms like wslc images), and wraps alias output at console width boundaries when writing to an interactive console.

Changes:

• Build a full-invocation alias list by discovering all registrations of the same command (including root-scoped equivalents) and formatting them with the current executable name.
• Wrap alias listings at console width only between alias tokens, preserving indentation.
• Add E2E coverage asserting the new alias listing format for a few representative commands.
