Solidify hand histories into one versioned shape that gets stored, replayed, and
exported — the foundation the tap recorder will emit into and RTO consumes.
- normalize_structured(): single guarantee of the contract shape — canonical cards
(unicode/10/case -> RankSuit tokens, unknown 'Ax'/'x' preserved), hero synced into
players[] (RTO finds hero via pos==hero_pos), schema_version stamp, and a
completeness summary so consumers skip suit-dependent math on partial hands.
Idempotent; runs on store AND read (legacy rows conform on the way out).
- list_recent_hands: has_structured flag so the export/RTO knows which hands have a
replayable body worth fetching.
- docs/HAND_HISTORY.md: the shared contract both repos cite (schema, conventions,
ownership rule, one-way HTTP coupling, transport endpoints).
- replaces the narrow _normalize_parsed (unicode-only) everywhere.
Card format chosen: lists of 2-char tokens (unambiguous, matches what Lyra already
stores + the viewer reads). Unknowns kept + flagged rather than dropped.
