test: Add comprehensive test suite (78 new tests, 291 total)

- Unit: Nmap command building, port parsing, IP validation, risk levels
- Security: Shell metachar injection (24 tests), SSRF prevention, credential scan
- Integration: Binary existence, persistence, serialization
- Functional: Scan profile flows, export, threat analysis, ARP parsing
- Frame: Singletons, presets, export formats, AI backends, enums
