fix(compile): implement abstract class traits across all types

Implement BaseCommand trait and other abstract class traits across
all command, downloader, io, package, and VCS driver types. Also
fix trait method signatures for composer_mut and io_mut to return
mutable references to Option rather than Option of mutable references.
