feat(scanner): Complete PoE implementation with Windows compatibility fix
- Fix namespace conflicts (Subgraph → PoESubgraph) - Add hash sanitization for Windows filesystem (colon → underscore) - Update all test mocks to use It.IsAny<>() - Add direct orchestrator unit tests - All 8 PoE tests now passing (100% success rate) - Complete SPRINT_3500_0001_0001 documentation Fixes compilation errors and Windows filesystem compatibility issues. Tests: 8/8 passing Files: 8 modified, 1 new test, 1 completion report 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
