* feat: introduce Capella and Deneb `full-node.md` lc changes * add switch-case and replace `[][]byte` with `[][]string` * return version name in http header * populate header and use `interfaces.ReadOnlyBeaconBlock` * fix lint * merge cases in switch case and replace `interfaces.ExecutionData` with `*ExecutionPayloadHeader` * minor fixes * refactor `createLightClientBootstrapCapella` and `createLightClientBootstrapDeneb` * use lightclientheader instead of different versions * fix failing `TestLightClientHandler_GetLightClientBootstrap` tests * fix lint * refactor handlers * refactor handlers more * refactor handlers even more * create conversions_lightclient * fix lint errors * add deneb and capella proto headers * update lightclientbootstrap proto struct to capella&deneb * update usecases * update usecases * resolve panic in header.GetBeacon * fix spacings * refactor core/lightclient.go * fix isBetterUpdate * use errors.wrap instead of fmt.errorf * changelog entry * fix lint errors * fix api structs to use json rawMessage * inline unmarshal * remove redundant nil check * revert remove redundant nil check * return error in newLightClientUpdateToJSON * inline getExecutionData * better error handling --------- Co-authored-by: Radosław Kapka <[email protected]> Co-authored-by: Inspector-Butters <[email protected]> Co-authored-by: Bastin <[email protected]>
