Add TODO section for future work: add a `--help` / `help` argument
handler to every personal skill so users can type `/<skill> --help`
and get a standardized help block (description, usage, arguments,
examples, see-also) without dispatching the agent.
Design sketch: shared lib at skills/lib/help-handler.md, integrated
as STEP 0.5 in each SKILL.md. Skills-external/gstack excluded — they
have their own convention.
Follow-up discovered while reviewing /validate — the new skill has
argument-hint but no --help handler, matching the state of every
other personal skill. Worth systematizing rather than one-off.
