feat(egress): implement PRD 0053 — DLP addon with Gateway API matches
Replace path_allowlist with Gateway API HTTPRoute match vocabulary (paths, methods, headers with AND/OR semantics) and add DLP scanning to the egress proxy: - Token pattern detection (AWS, GitHub, Anthropic, OpenAI, Stripe, JWT) - Known secret detection (EGRESS_TOKEN_* with base64/URL/hex variants) - Naive prompt injection detection (disclosure + credential, jailbreak) - Per-route DLP configuration via manifest dlp block - Inbound response scanning with block/warn severity Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
