chain of provider names as it propagates back up to the caller. With an empty `dependency_path`
(the error never passed through a resolution frame) `_render_body` returns the base message
unchanged.

Empty `__slots__`: each concrete error declares the `_base_message`/`dependency_path` slots
itself, avoiding the `TypeError: multiple bases have instance lay-out conflict` that a slotted
mixin combined with an `Exception` subclass would otherwise raise.
