- Reference logo.png from the repo instead of the dead raw.github URL
(the logo lives in the common submodule, which Gitea can't serve from
a relative path, so a copy sits next to screenshot.png)
- Drop the section emojis and horizontal-rule separators
- Add supported versions, the built-in mods, installation (Modrinth,
releases), network use (Mojang session sign-in; the access token never
reaches the Saturn server), building from source with submodules, and
a pointer to the version guide for multi-version changes
