- `releasesToFeedItems` is called to convert release structs to feed items, which is then used to render RSS or Atom feeds.
- Optimize the loading of attributes for the releases, introduce `ReleaseList` type which uses caching to load repository and publishers. It also no longer loads release attachments and downloads counts as that is not used in feed items.
- Optimize the composing of meta by introducing caching, this operation is especially slow when the owner is an organization.
- Add unit test (ensures new `LoadAttributes` works correctly).
- Add integration test (ensures that feed output is still as expected).
Loading https://codeberg.org/forgejo/forgejo/releases.rss reduced from ~15s to ~1s. (It is currently is deployed on codeberg.org)
