fix(config): keep installed versions eligible with release age

 Supports relative durations (`7d`, `6mo`, `1y`) and absolute dates (`2024-06-01`). For most
 backends, this only affects fuzzy version resolution, such as `node@20` or `latest`.
 Explicitly pinned versions like `node@22.5.0` bypass the filter.
+Versions that are already installed also remain eligible: `minimum_release_age` limits remote
+version selection and does not make an installed version inactive.
 
 Capability depends on the backend:
