feat(job-array-single-wal-record): add WAL_JOB_ARRAY_SUBMIT record type

Browse source 
Adds the array-shaped WAL entry type (distinct from WAL_JOB_SUBMIT,
value 11 in the unused WAL_JOB_* gap) and classifies it WAIT-mode via
wal_classify, matching the single-job type's commit-barrier semantics.
No dispatch/apply wiring yet -- foundation for task 2.x/3.x.

Task 1.1 of job-array-single-wal-record.
