A very basic POC. Need to refactor to generate completion structure before passing to the template to avoid repeated computations. What works: * Real zsh completion (not built on bash) * Basic flags (with long flag and optional shorthand) * Basic filename completion indication (not with file extensions though) What's missing: * File extensions to filename completions * Positional args * Do we require handling only short flags?
