fix(reloader): create target namespace

[Matthiator]

📝 Summary

Adds the missing Namespace manifest to the Reloader umbrella chart. Argo CD disables automatic namespace creation, so Reloader otherwise remains OutOfSync on a fresh cluster.

The fix was moved from kubara-io/kubara#518 because chart templates now belong in the external catalogs repository. The independently releasable general catalog is bumped from 1.0.0 to 1.0.1.
