Design for making the man-page-style comment header above each function
reachable at runtime via -h/--help, instead of hand-writing 40 more menus.
One renderer (__fish_help_header) parses the .fish source at call time and
prints the header to stdout; each call site is a single line. Audits all 79
published functions that lack help today into 35 shadow/pass-through exempt,
4 prompt-hook exempt, and 40 to convert, with a one-line reason each.
Corrects the baseline counts (109 published functions, 30 with menus, 79
without) and records two pre-existing defects found while auditing.
Note: AGENTS/ is gitignored upstream, so this file is force-added.
