fix(records): enforce per-area lifecycle summaries

[localai-org-maint-bot]

Outcome

Closes a fail-open gap in ROAD-V1-A6: check-agent-record.py validated only the engine lifecycle summary grand total, so named area rows could drift while the 131-row total remained correct. The checker now validates all ten named areas against their canonical ## sections and retains the total gate.

The new enforcement immediately found three stale snapshots (Engine, KV, and Serving); this PR reconciles those cells without changing any underlying lifecycle state or support claim.

Design

I evaluated three approaches:

1. keep total-only validation, which preserves the bug;
2. hard-code line ranges, which breaks as sections grow;
3. map each canonical summary label to its canonical section heading and derive counts from parsed claim rows.

The PR implements option 3. It rejects missing, duplicate, unknown, non-numeric, or drifting area cells. The design/spike is recorded in .agents/specs/agent-record-area-summary-integrity.md.

TDD evidence

RED first: a mutation moved one count from INVENTORIED to ACTIVE in Engine and scheduling while keeping the grand total unchanged. Before implementation it failed because check_engine_summary_lines did not exist. After implementation, the mutation is rejected with the area-specific mismatch.
