refactor: rename Outpost to Adversary/Security and drop outbound scanning
- Rename OutpostMiddleware -> ChannelScanner - Rename OutpostProxy -> AdversaryProxy - Rename OutpostVerdict -> ScanVerdict - Remove Outbound/AgentResponse scan contexts and outbound scanning logic - Update all strings 'OUTPOST' to 'ADVERSARY' - Outbound PII detection moved to roadmap
