Completes the bridge cross-chain release leg the recon flagged as missing. - internal/bridgeattest: the ONE canonical definition of the bridge-transfer attestation seam between B (bridgevm) and M (mpcvm). M threshold-signs a domain-bound bridge-transfer digest; B and every EVM gateway holding the group key's address verifies before mint/release. Domain-bound + replay-safe; test proves a signature over one transfer verifies for THAT transfer and no other. - evmclient.go: the concrete EVM ChainClient B instantiates per external EVM (Zoo 200201, Lux testnet C 96368) — chainClients was never populated because the interface had SendTransaction but no concrete EVM client; B could not broadcast a release. Now wired via evmByChainID in factory. - release.go: on a confirmed lock/burn in an accepted block, B builds the destination release call, obtains + verifies M's threshold attestation, and broadcasts to the destination gateway. Both directions (Zoo<->Lux). - attest.go: injects the two runtime deps (Warp->M, KMS relayer key) as clean interface boundaries rather than hard-wiring transports.
