docs(roadmap): currency landed; M4 is next

Both roadmaps still described the copper currency change as pending. It is
merged. The marker moves to M4, M8's line now says what it still owes (the
price table — nothing is priced yet), and a "Landed out of band" section
records the two items that shipped outside a milestone: the currency value
type, and the once-per-reply move cap its review turned up.

+- ✅ **A move applies at most once per reply** — found by the review of the above. `TagExtractor` returns *every* tag occurrence and `MoveValidator` is a membership test, so a model repeating a tag N times picked an amount **in unary** (§2 breach: the AI choosing a number). Now deduped by (name, id) across a reply, and `adjust_disposition`'s `MAX_DELTA` caps the reply's **net** swing rather than each tag — it was per-tag, so three `+15`s moved standing by 45, the exact "wholesale swing" the constant forbids. *§2: state · goal: the bounded vocabulary stays bounded.*
