[Skidamek]

Adds velocity plugin. Basically port of server side mod version to velocity plugin.
Resolves #224

This is at all not ready, however what already does work is:

• modpack generation
• modpack hosting

Whats to do:

• login packets
• commands
• fix config

The current implementation assumes the server owner manages the modpack via their Velocity server. This approach simplifies managing a network of servers sharing the same modpack, as you don’t need the AutoModpack mod on each individual server—especially for plugin-based setups where AutoModpack does not even exists yet.

However, it may not work well for servers requiring different mods on different servers under the same proxy. Issue #223 should address this limitation once implemented.

This PR adds basic Velocity plugin support, aligning its features with the server side mod version (except those requiring mixins or loader-specific detection).

For future, proxy specific exclusive options like some kind of under proxy server connection separate PRs/Issues are welcome.

Is this functionality in a state where it could be merged into the main branch while more work continues? This alone would be a massive help to a lot of people.
