pkg/dchain: store original outcome under seen:<txID> and return it verbatim on replay so a
deduped clob_place is distinguishable from a genuine reject (was returning StatusRejected →
reverted the EVM tx that re-executes ~5x). BookDepth read accessor. cmd/dvenue = the dial-able
venue D-Chain ZAP listener (badgerdb + vm.Initialize + rpc.Listen + RegisterCLOB + production
sealer) the 0x9010 precompile + dexvm proxy point at; cmd/dclient = native-ZAP e2e driver.
zapdb v1.10.0→v1.10.1 (cloud-free, cgo blocker resolved on the v1 lineage). Tests green.
