Full Release Notes

## What's Changed

> [!WARNING]
> The Facebook source (Meta CT) has been removed in this release after Meta discontinued the upstream API.
>
> If you reference this source in automation, CI jobs, or saved source lists, remove it from those configurations.
> For most users, the practical impact should be low, since the integration was already non-functional, and this change mainly removes related errors and confusion.
