The feature

I would like my shell bash/zsh to autocomplete the possible commands when pressing tab, aka $ immich <tab>.

The CLI is simple so it's more nice to have then a high priority feature. I create this just to track progress. Sometimes the parsing libraries can generate thse files just fine by passing a --bash-completion flag. I confess I haven't looked at the CLI source code.
