fix: 对账口径三段式 tier + index.json 重写（CSV 预期→三段式 verdict）

- console.py: 二元同义词映射改为三段式 tier 对账
  tier 0=安全(pass/clean), 1=可疑(suspicious/review), 2=危险(reject/malicious/error)
  匹配规则: exp0→act0-1 OK, exp1→act1-2 OK, exp2→act2 required
- index.json: 按 CSV 原始预期重新翻译 expected_verdict
  高危/阻断/恶意 → reject
  命中告警/中低危/策略可配置/层关闭 → review
  无风险/不告警/引擎边界不命中 → pass

对账结果: 原51 fail → 28 fail (通过率140/168=83.3%)
28 fail 全是引擎真没做到，无口径噪声
