v2.4.0 — The split floor: station console + pick-to-tote

• STATION-02: Desktop station console — keyboard-first pack bench over the same STATION-01 services; L17 golden proves console ledger is byte-identical to PDA (#67)
• SPLIT-01: Pick-to-tote split mode — third dispatch option (Walk | Station | Split); tote as association with full lifecycle (bind → carry → release → rebind), named guards (TOTE_IN_USE / TOTE_REQUIRED), waiting-totes bench view (#70, #74)
• S4-HF1: Reconciliation poll now ingests through the webhook path — line-complete orders, zero-line self-healing, normalized order names (#71)
• Karma clock-tie flake eliminated for good (#72)

Rollback: re-deploy v2.3.0 (single migration in range is additive — safe). Release smoke: PASS 5/5 (ledger witness included — L17).
