A launched bundle serves under the module the runtime names (hq ADR 0193)

serveRegisteredOverStdio lists the registrations of the module named by MESH_SERVED_MODULE by
their own names and every other registration as <seat>.<verb>. Before, the first registration
was taken for the module's own, so a bundle registering its seat first listed the seat's verbs as
its own tools. Contributors are given the process's environment, the bundle's own. 0.1.4.
