Email Quality Auditor

Use when the user asks to "audit an email program", "is this campaign safe to send", or run a pre-send go/no-go on their own exported email data; runs SEND EQS scoring with S1/S2/N1/D1 veto checks and a SHIP/FIX/BLOCK gate, and emits a gated audit artifact. Not for building deliverability setup — use deliverability-qa; not for designing lifecycle flows — use email-sequence-designer. 邮件质量审计/EQS评分/发送前放行
