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

Browse source 
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.

* Frame-only wire types for the controller<->worker job-state
* reconciliation exchange (OPCode_jobStateQuery/OPCode_jobStateReport) --
* same "no live C struct" convention as capnp_host_admin_state_t/
* replay_cluster_t above (see controller.capnp's comment at `struct
* JobStateEntry`). An enum-typed capnp field (status) maps to a plain
* `int` here, not a separate named C enum type -- mirrors the existing
* HostRole/JoinData.role and SchedAdminAction/sched_admin_req_t.action
* convention (the generated `enum JobStateStatus` in controller.capnp.h
* already supplies the JobStateStatus_running/finishedOk/finishedFail/
* unrecognized constants for callers that want them). This is schema-only:
* the C-side send/receive/encode/decode logic is later tasks (1.4 wire
* codec helpers; 6.1/6.2 controller wiring; 4.x worker wiring). */
