Zod schema for an `activity` — a first-class executed session (the
executed side of a SessionMatch). Shape mirrors the health records'
`{ summary, krd? }` split: a mandatory summary for list/match reads plus
the optional full KRD payload attached when the source provides recorded
detail (records/laps/sessions).
