The latest release is now the source of truth for plugin versions, so
the registry version only serves as a display fallback. Validate its
format only when present.
Replace the tag-pinned release lookup with the repository latest
release endpoint. Derive the plugin version from the release tag,
validate it, and attach an optional token to API requests to raise
the rate limit.
- Introduced logic to handle plugin unloading during updates to prevent conflicts with loaded plugins.
- Preserved existing plugin configurations during updates, ensuring seamless transitions and maintaining custom fields.
- Added support for reloading the configuration after management saves changes.
- Enhanced unit tests to validate unloading, configuration preservation, and reloading behaviors.
