Closes #801 Adds MerkleReplaySafety.v with three fully-proved theorems: - merkle_deterministic: same leaf inputs => same Merkle root (congruence) - receipt_no_replay: distinct window counters => distinct receipts - monotonic_window: S n <> n (window counter is strictly monotonic) Also adds docs/phd/artifacts/coq_citation_map.json mapping: MerkleReplaySafety.merkle_deterministic -> trinity_merkle_agg.v MerkleReplaySafety.receipt_no_replay -> ledger_receipt_v2.v Verified: coqc 8.20.1 exits 0, zero Admitted.
