Adds a monotonic-timestamp guard (require_monotonic_timestamp) to claim() and clawback(), independent of the existing same-ledger replay check. Rejects a fund-moving call if the ledger timestamp is behind the last observed value, as defense-in-depth against a manipulated or anomalous timestamp reaching vesting-calculation logic. Adds claim_rejects_timestamp_regression and clawback_rejects_timestamp_regression tests. Documents the mechanism in contracts/vesting_escrow/README.md.
