feat(worker-rejoin-resync): add worker reconciling status type (task 1.2)

Browse source 
Add XCE_WORKER_RECONCILING status bit (0x00800000, next in the existing
sequential bitmask) + IS_WORKER_RECONCILING macro mirroring
IS_WORKER_UNAVAIL's shape, and resync_state_t (round_token,
queried_jobids array+count, deadline) referenced via a nullable
worker_t.resync pointer -- NULL when no reconciliation round is
outstanding. Compiles and is reachable, unused by any caller yet.

- Observable completion: the schema builds cleanly and the new message/opcode/config-field definitions are visible in the generated bindings
- _Requirements: 2.1, 2.2, 3.5, 3.7, 5.3, 8.1, 8.2, 8.3_
- [ ] 1.2 (P) Add a worker reconciling status and round-tracking state
- [x] 1.2 (P) Add a worker reconciling status and round-tracking state
- Add a new worker status value meaning "job-state reconciliation outstanding for this host"
- Add a per-worker reconciliation-round structure capable of holding a round identifier, the set of queried job IDs, and a deadline
- Observable completion: the new status value and round structure compile and are reachable from the worker record, unused by any caller yet
