PHPStan failed on 7.4 after updating to 0.12.99, and I figured it was less hassle to just do this than fix the build. In any case, we stopped shipping 7.4 months ago, and warned at 3.22 release that 7.4 support would soon be dropped.
this allows entities to exist outside of generated chunks, with one caveat: they won't be saved in such cases.
Obviously, for player entities, this doesn't matter.

This brings a significant performance improvement to login sequence handling, reducing CPU cost of `PrepareEncryptionTask` by over 90% and `ProcessLoginTask` by over 60%. It also allows us to shed a dependency.
this doesn't implement the server-side logic for the "stickiness" (slowdown) because we don't have the system needed for it yet.
It also doesn't have parity with vanilla on the damage.
while this is a bit hacky outside of the protocol namespace, it makes it much easier to use the protocol library for alternative purposes, such as for a client or MITM proxy.
It also removes all but one remaining core dependency of the protocol library, making it very close to being able to be separated from the server core entirely.
WorldProviders now have the following requirements removed:
- __construct() is no longer required to have a specific signature
- static isValid() no longer needs to be implemented (you will still need it for registering, but it can be declared anywhere now)
- static generate() no longer needs to be implemented
This paves the way for more interesting types of world providers that use something other than local disk to store chunks (e.g. a mysql database).
WorldProviderManager no longer accepts class-string<WorldProvider>. Instead, WorldProviderManagerEntry is required, with 2 or 3 callbacks:
- ReadOnlyWorldProviderManager must provide a callback for isValid, and a callback for fromPath
- WritableWorldProviderManagerEntry must provide the same, and also a generate() callback
In practice, this requires zero changes to the WorldProviders themselves, since a WorldProviderManagerEntry can be created like this:
`new WritableWorldProviderManagerEntry(\Closure::fromCallable([LevelDB::class, 'isValid']), fn(string ) => new LevelDB(), \Closure::fromCallable([LevelDB::class, 'generate']))`
This provides identical functionality to before for the provider itself; only registration is changed.
