feat: add post-pipeline hooks (KIN-003)

- core/hooks.py: HookRunner с CRUD, run_hooks(), _execute_hook(), логированием
- core/db.py: новые таблицы hooks и hook_logs в схеме
- agents/runner.py: вызов run_hooks() после завершения pipeline
- tests/test_hooks.py: 23 теста (CRUD, fnmatch-матчинг, выполнение, таймаут)

Хуки запускаются синхронно после update_task(status="review").
Ошибка хука логируется, не блокирует пайплайн.
