test(raft-ha-core-safety): machine-checkable walcompare report (task 1.1)

Browse source 
Per-member (lsn,term,pcrc,present) report + committed-vs-uncommitted
divergence classification via walcompare_report()/--report. Soak signal
(OK/exit-code) preserved. 4 new unit tests, all GREEN.

> **Hypothesis discipline:** the term-blind bypass is the primary hypothesis, not proven sole cause. Task 1.3 must reproduce the *live* divergence first; a green synthetic unit test over a still-red soak does not satisfy 1.1/8.1.
- [ ] 1. Foundation: deterministic chaotic harness and live-divergence reproduction
- [ ] 1.1 Extend the divergence detector to a machine-checkable per-member report
- [x] 1.1 Extend the divergence detector to a machine-checkable per-member report
- Extend `walcompare` to emit a parseable per-member `(lsn -> term, payload-crc, present/MISSING)` report over the committed prefix, and classify each divergence as committed vs uncommitted
- Observable completion: `walcompare` prints a parseable per-member report and a committed-vs-uncommitted classification; the existing soak still detects the round-3 LSN divergence through it
- _Requirements: 7.1, 7.5_
