v0.4.0

Release 0.4.0

✨ New Features

• Defer & Recall for Context
  States can now postpone processing of an incoming message using context.defer() and later resume with context.recall().
  This enables advanced workflows such as multi-step authentication flows where incomplete inputs can be held until sufficient data arrives.

  • Added defer() and recall() methods to Context ABC
  • Added notify_income_deferred / notify_income_recalled hooks to StateMachineSubscriber
  • Updated all state machine implementations to support deferred message queues
  • Added tests and examples for defer/recall patterns

🛠 Fixes

• Fixed test_anyio.py mypy false-positive issue
• Fixed context manager & return handling

📚 Documentation

• Updated README to highlight the new defer & recall features
