2569718930@qq.com 20516000a2 Clarify scan terminal service boundaries
The scan terminal service had accumulated cache, payload, filtering, AI prompt, AI merge, METAR gate, ranking, and city-row construction details in one file. This splits those stable responsibilities into focused modules while preserving the endpoint payload shape and existing behavior.

Constraint: User-visible behavior and release version must remain unchanged for this internal refactor

Rejected: Rewrite the terminal scan flow around a new abstraction | too risky while production behavior is being stabilized

Confidence: high

Scope-risk: moderate

Directive: Keep scan_terminal_service.py as orchestration; add detailed rule changes to the focused modules instead of re-growing the service file

Tested: py_compile for extracted modules; ruff check .; pytest tests/test_scan_terminal_modules.py tests/test_web_observability.py; full pytest; npm run test:business; npm run build; git diff --cached --check
