feat: resolve trivial todo!() sites with existing constructors

Replace todo!("VersionParser::new()") with VersionParser::new() at 6
call sites (array_loader, base_command, create_project_command,
vcs_repository, http_downloader x2) and EventDispatcher::io_clone with
self.io.clone(). All targets already exist on their types.
