Hey this looks pretty good

.. but i have a suggestion, instead of using error stacktrace to find out the caller, it could be better to utilzie commandkit's context data (available in commands and events) to determine the caller at higher level. See how the internal logger does this https://github.com/underctrl-io/commandkit/blob/be5ac1f1fa49ee659a82ca438fdc265699755749/packages/commandkit/src/logger/DefaultLogger.ts#L78
