Warns, at most once per module for the lifetime of the BEAM node, that a reactor, reducer or projection is relying on its module name as its identifier.

Renaming or moving the module then silently resets Chronicle's observation position for it, because the id changes along with the name. Discovery can run more than once in a client's lifetime (once while logging at startup, again through Chronicle.Client.discovery_report/1 or mix chronicle.discover), so the warning is kept behind a :persistent_term guard keyed by module rather than emitted unconditionally.
