zeekay c64a1457a8 refactor: Simplify orderbook to pure Go default with optional CGO
Clean architecture following Go principles:
- factory.go: Pure Go implementation (default, no CGO)
- factory_cgo.go: C++ optimized version when CGO=1
- orderbook.go: Standalone Go orderbook implementation
- cpp_orderbook.go: C++ bindings for high performance

Also includes:
- Vault execution integration with orderbook
- dex-api-server command for REST/WebSocket API
- E2E test scripts for API validation
- Documentation site scaffolding
