feat(worker-rejoin-resync): define reconciliation wire protocol (task 1.1)

Add OPCode_jobStateQuery/OPCode_jobStateReport, JobStateEntry/
JobStateQuery/JobStateReport structs (paginated, mirroring JobData/
WorkerData/ResourceVals' {ntotal,pos,count} shape), and
workerResyncWindowMs/workerResyncTimeoutMs ClusterConfig fields to
controller.capnp, plus the companion typemap.h/clusterconfig.h C type
declarations this codebase's capnp $C.mapname codegen requires to
compile. Both new opcodes are fire-and-forget (Request.body union only,
no RequestReply arm), matching design.md and the push/notify precedent.
