Add some method of Distribution of custom AIs

[Arch-Shaman]

There should be a way to distribute AIs via the server much like mods. Perhaps some sort of subscription system that queues downloads from the server automatically?

See: https://github.com/ZeroK-RTS/Zero-K/issues/5212

Hmm what exactly is needed? If we make them dpeendency of game they will be updated automatically. What scenarios do we need to solve?

This is about an AI for a mod (not for normal ZK). Mods (and maybe AIs for mods? idk) have their own release cycles independent from normal ZK so if we distribute them as a dependency of the game they would still have to wait for a ZK release to sync up I think.

So the scenario looks like this:

• ✅ mod has a new version (for example v1 -> v2) and needs a new AI version to go with it.
• ✅ modder uploads mod_v2.sdz to ZK infra.
• ✅ modder updates the json at (for example) https://zero-k.info/Mods/Edit/1 and changes game version. Now the correct version of the .sdz will be downloaded automatically when hosting the mod on the server.
• ❌ modder can't upload ai_v2.dll to infra, and can't specify that mod_v2.sdz goes with ai_v2.dll. So AI distribution is not resolved automatically.
• ❌ when players host mod_v2, they still have old ai_v1 which crashes -> ZeroK-RTS/Zero-K#5212
• ❌ ZK doesn't plan to have a release anytime soon so even if all mod AIs were bundled with ZK we would be in the same place we are currently.

Sounds like perhaps AIs should be type of "resource" similar to map and mod and downloadable via normal means. Then they could be a dependency of mod.
