test: add ops-bot evolution cases

[upsearchmain]

Summary

• Add 30 ops-bot JSONL evaluation cases under cases/ops-bot/cases.jsonl.
• Distribution: 10 alert severity, 10 runbook step, 10 postmortem.
• Keep a consistent top-level JSON shape: id, skill, category, input, expected, judge.

Verification

• test -f ~/hermes-evolution/cases/ops-bot/cases.jsonl && echo test -f: OK
• wc -l ~/hermes-evolution/cases/ops-bot/cases.jsonl -> 30
• /usr/bin/python3 JSON parse command -> OK
• distribution/shape check -> rows 30, categories 10/10/10, shape_distribution: OK
• git diff --check origin/main...HEAD -> exit 0

Self-Review

• P1: Scope came from task, v5 PART 13/15, skills README, edge cases, and acceptance section 7.
• P2: One JSONL data file only, no scripts or extra abstractions.
• P3: Only ops-bot cases file is tracked in this branch. Other profile cases were not touched.
• P4: Success criteria were verified against the exact ~/hermes-evolution path.
