ViaVersion/ViaFabricPlus — reverse-engineered prompt

Build me a Minecraft Fabric mod for the current client that lets me join servers from basically every major Minecraft era without switching game versions. I want it to work on the newest Minecraft client only, be clientside only, and affect multiplayer only, not singleplayer worlds.

The main goal is that older servers should feel as close as possible to how they originally played. Please handle the version translation so I can connect to release, beta, alpha, classic, April Fools, combat snapshot, and Bedrock servers when possible, and smooth out the weird stuff that usually breaks, like movement, block and entity interactions, and visual quirks. If Bedrock support has some missing features, that is fine, just make it usable and honest about limitations.

Please structure it like a real mod project someone can build and run, and include basic docs for install and usage. If there should be a small developer facing API for integrations, include that too. You can look up current docs online if needed.
