docs(recipes): annotate the keys that do nothing

phase_config::DECLARED_BUT_UNREAD lists four keys the recipes set and
nothing reads. security_hardening.toml already carried a "what is real
here and what is decoration" section and annotated its own dead keys
inline; the other five did not, so `produces = ["md"]` and
`loop = "until_no_more_int_items"` read like settings.

The risk was never the dead keys themselves — it is a reader taking
`loop = "until_no_more_int_items"` for a loop. Each now says it is inert
and points at the registry. They stay because they state the intent.
