- AssistantService теперь принимает ForecastService в конструкторе (раньше создавал new ForecastService() внутри analyze/advice) - infrastructure/cli/main.py: _build_services() — composition root, собирает граф ForecastService, ScenarioService, AssistantService, CurrencyConverter - Все CLI-команды используют _build_services(model) вместо прямого new - test_ai.py: обновлён под новый контракт AssistantService Tests: 67/67 pass.
