Enable dynamic extension exports and small behavior fixes across events and flow modules: - events/__init__.py: Added _extension_exports and extended __getattr__ to lazily resolve registered extension values or import paths. - events/event_bus.py: Implemented off() to unregister sync/async handlers, clean handler dependencies, and invalidate execution plan cache. - events/listeners/tracing/utils.py: Added Callable import and _first_time_trace_hook to allow overriding first-time trace auto-collection behavior. - events/types/tool_usage_events.py: Changed ToolUsageEvent.run_attempts default from None to 0 to avoid nullable handling. - events/utils/console_formatter.py: Respect CREWAI_DISABLE_VERSION_CHECK env var to skip version checks in CI-like flows. - flow/async_feedback/__init__.py: Added typing.Any import, _extension_exports and __getattr__ to support extensions via attribute lookup. These changes add extension points and safer defaults, and provide a way to unregister event handlers.
