KommonLogger
interface KommonLogger
Minimal logging seam so shared-library modules (sync, auth-session bootstrap, etc.) can log without depending on any specific logging framework (Timber, java.util.logging, etc.).
Consumers bridge this to their own logging stack (see TimberLogger for a ready-made Timber bridge, or implement it directly against their own facade). NoOpLogger is the default so nothing breaks if a consumer doesn't wire one in.
