fix(memory): an uncredited save cannot change the words a note was credited on

foldFacts took `said` from every person observation of a note but set `yours` only from credited
ones. So after a credited "Use pnpm" (said: "always use pnpm"), a second remember() of the same
note with an invented instruction in `said` failed grounding yet replaced the quote, and the
invention appeared as "you said" in the always-on "From you" section.

A credited note now keeps its phrasing, quote and date together: only another credited
observation changes them. Its source is still counted. After the person removes it, an uncredited
save is recorded as before and stays inactive.
