fix(cache): enable dist archive caching for all commands

files_cache was Option<&Cache> and install_from_lock always passed None,
so downloaded zip/tar archives were never cached. Make the parameter
non-optional (&Cache) and wire it through every command that downloads
dist archives (install, update, require, remove, create-project,
archive). The Cache internally respects --no-cache via its enabled flag,
so the Option wrapper was unnecessary.
