docs(job-array-one-based-index): document the supported array syntax (task 9.3)

src/docs/xce.md gains a 'Job arrays' section: name[1-N] and name[1],
numbering from 1, the API-server limit (default 1000, at most 32767),
<array-id>[k] and <array-id>[a-b] selection (with the peek/restart
caveat), XCE_JOBINDEX, the harness jobsub -a N / $jobid[k], and every
LSF array feature this release does not support. The superseded
statements in job-array-single-wal-record and xce-test-e2e-primitives
are annotated (history kept), the controller-job-cleanup and
job-dependency briefs describe 1-based numbering, and the roadmap gains
an entry.

checkpoint: bug-851 root cause + raft TLA+ conformance spec family

Investigation & fixes (failover committed-job loss):
- root-cause bug-851 on an owned 3-node cluster: chaotic failover causes
  silent committed-prefix divergence (WAL hdr.term always 0; two leaders
  per term; no (term,lsn) reconcile). Evidence in repro-851/ + INVESTIGATION.
- live-validated fixes 848/849/850 (recovery-on-promotion, advertise real
  applied_lsn, persist-layer contiguity guard); add waldump WAL inspector.

Specs (strict raft.tla conformance — library owns the log):
- TLA-gap-analysis.md: impl vs raft/raft.tla, gaps G1-G6.
- raft-log-replication, raft-commit-safety, raft-sim-conformance: extend
  src/lib/raft to own log/commit/verification via callbacks (specs generated,
  cross-spec review passed).
- ha-term-safety: controller-side adapter + config marker (R1-R7); design done.
- config-upgrade-snapshot: R8 descoped here (deps entity-bearing-snapshots, bug-857).
- roadmap + buglog (851/854/857) + .wolf knowledge updated.
