[0.21.0] - 2026-04-26

User-turn ledger line: UserTurnLine (#94, follows #74). New LedgerLine kind (user_turn) with matching appendUserTurns writer, queryUserTurns reader, and isUserTurnLine guard. Append-only and dedup'd through the same ~/.relayburn/ledger-index namespace as turns / compactions / relationships / tool-result events via userTurnIdHash keyed on (source, sessionId, userUuid). rebuildIndex re-indexes the new kind. Old readers that don't recognize kind: 'user_turn' simply skip the line — the existing per-kind guards already filter to known kinds. Persists the per-user-turn block sizes the reader started emitting in #74 so consumers can read them back without re-parsing source session files; backfilling user turns into existing ledgers is not done automatically — see follow-up.
