[Alystrasz]

For a detailed description, see launcher PR: R2Northstar/NorthstarLauncher#828

Supercedes #824.

Testing (RequiredOnClient mod version enabling)

Test scenarios

Core mods

Launch game and join any server:

with `Northstar.Client` local version not matching server version (connection should be allowed);

Nothing special should appear in your logs here.

with `Northstar.Client` disabled (mod should be enabled before connection).

[2024-08-31] [00:33:19] [SCRIPT UI] [info] Enabled "Northstar.Custom" (v1.19.0) to join server.

Gamemode mods

Install several versions of a same mod (Parkour v0.2.0 + v0.2.1 for instance) then:

Enable/disable any version in any order through the mods menu (should work fine);

multiple_versions_handling.webm

Disable both versions and join a Parkour server (mod with matching version should be enabled);
