Uninstall Workflow

[ktwrd]

This PR adds an uninstall CLI sub-command and wizard option for uninstalling the target game. Before deleting the sourcemod mod folder, it will check if all of the following conditions are met;

• Is the game actually installed (RunnerContext.current_version.is_some())
• Is the game not running (with crate::helper::is_game_running where mod_directory is from RunnerContext.get_mod_location())

If any of those conditions are not met, an error will be returned and will not allowed the user to uninstall the game (if it is even installed).

I'll have a looky

I can't see anything inherently wrong with the modifications, but do make sure to test (and not do a crowdstrike).

Looks good, pls test (including edge cases).

I tested it on W10 (w/ OF in the default sourcemod folder) last night, but I'll check it on my Debian install and my Steam Deck tonight.

Tested on my windows install. Need to rebase from develop since #30 was merged.
