fix: resolve lint, type-check, and test failures

- B904: raise KeyboardInterrupt from err in cli_provider.py
- mypy: add TYPE_CHECKING import for SQLiteConversationStorage, annotate
  _initialized class var in TaskScheduler, fix Match type params and
  Returning Any in create_agent.py
- tests: mock aget_llm_response in 3 integration tests that fail when
  network is blocked but OPENAI_API_KEY is set
- flow.py: use asyncio.run_coroutine_threadsafe() instead of asyncio.run()
  when a loop is already running in ask() and say()
- cli.py: fix threshold=0.0 treated as falsy by using `is not None` check
