What

Add a public EventBus.remove(event_pattern, handler) method so callers can unsubscribe a handler registered with EventBus.on(). Returns True if the handler was found and removed, False otherwise.

Also extract the event-key resolution from on() into _get_event_key() and reuse it in on() and remove(), and refactor expect() cleanup to use remove().

Why

There is no way to unsubscribe after EventBus.on() — the only cleanup path is expect()'s internal self.handlers[...].remove(...). Closes #5.

How tested

• Added tests/test_remove_handler.py (4 cases: by class, by string name, scoped removal, wildcard *).
• Core suite: 63 passed.

Summary by cubic

Adds EventBus.remove() to unsubscribe a handler registered with EventBus.on(). Returns True if the handler was found and removed, False otherwise. Closes #5.

Changes

• Extracts event-key resolution into _get_event_key() and reuses it in on(), remove(), and expect() cleanup.
• Adds overloads mirroring on() so typed handlers remain valid when removed, and drops the event key from the registry once its last handler is gone.
• Adds tests covering removal by class, string name, scoped handlers, and * wildcard.
