Overview

Turns a CompletionSpec into a bash complete -F script. See SPECIFICATION.md §4.1: a static, case-statement walk over COMP_WORDS resolves which node the cursor is under, then compgen -W fills COMPREPLY from that node's children and option flags, with compgen -f added where an argument is a file (§4.3).

Deliberately avoids bash associative arrays (bash 4+ only): macOS still ships bash 3.2 as /bin/bash, and this script is meant to be eval'd from exactly that.
