* Data-less provider that signals to direct dependents that this target is a runfiles library.

* <p>Rules that find this provider advertised by a dependency may use this as a signal to generate
* code that helps with runfiles discovery, e.g., by providing a constant containing the name of the
* repository that defines the rule.
*
* <p>Bazel itself uses the presence of this provider on a rule as a sign that it should include the
* repository mapping of the repository containing the rule in the repository mapping manifest of
