    feat: cross-contract cumulative conservation invariants
    
    - vault: add TotalDeducted storage key + get_total_deducted() view
    - settlement: add TotalReceived storage key + get_total_received() view
    - test_cross_invariant: 64-seed x 48-step end-to-end conservation check
    - docs: update vault.json and settlement.json interface summaries
    
    Closes #539
