handle_jobsubmit classifies (first_jobid, array_size) before the field
checks, the before-event hook and any registry access: a tagged array
starting at index 0 is answered with the new E_XCE_ARRAY_START0 and an
ERROR log asking for the client to be upgraded (7.1, wins per 7.9);
size 0, tags 2/3, untagged multi-element submissions and arrays whose
last element exceeds 32767 (checked without addition) get -EINVAL.
Nothing is stored for a rejected submission. This also closes a crash:
a size-0 submission used to reach payload building and overflow calloc.
Existing array tests move to tagged block|1 first IDs.

idgen_array() allocates the next whole 32768 block and returns its
first element (array tag, index 1), refusing n outside 1..32767 and a
block past the 20-bit sequence (-EOVERFLOW, context unchanged). The
reset-on-new-second step is shared with idgen() via idgen_tick_locked();
idgen() itself is unchanged until task 9.1.

parse_jobid() keeps its signature but is now bounded and NULL-safe: a
bare identity returns the exact ID, [k] the element ID, and a range, any
rejected selection (5.7, 5.8, 5.14, 5.15) or a NULL argument returns
-EINVAL with *jobid = 0. Fixes the strlen-before-NULL-check crash and
the atoi overflow; regex parsing is gone.

parse_jobsel() parses c-a-ts-seq with an optional [k] or [a-b] under a
fixed grammar and check order (syntax, field widths, array-identity
alignment, element bound, reversed range), saturating digits so an
oversized number cannot wrap; plus is_array_tag(), jobsel_element_id(),
jobsel_strerror() and JOBID_FIELD_MAX_* constants. The selection-cases
conformance table runs in the libxce suite.

Spec for numbering job-array elements from 1 (bug-1896): approved
requirements, a design reviewed over 20 rounds until clean (log in
research.md), and a 30-task plan. The design review found two live
apiserver defects, logged here: bracketed job_id/job_name filters are
never evaluated (bug-1898) and ControlJobByID re-dispatches earlier
selections (bug-1899).
