Clarify that disabling auto-save does not stop all saving operations. This addition explicitly mentions that the world will still save on shutdown and explains the intended purpose of the method.
Player info packets carry chat state to other clients since the
introduction of chat signatures. Queuing these packets while force
pushing chat packets allows for potentially inverted packet order, which
may cause chain corruption on clients.
Fixes compilation issues for plugins from recent API addition with double-annotated parameter (JetBrains annotations are type-use and parameter, so nonnull array of nonnull elements ends up with duplicates)
If the player is not affected by movement through blocks, then
storing the movement would eventually invoke logic to apply effects
caused by moving through such blocks. For example, moving through
a portal in spectator mode and then later switching to creative mode
would portal the player.
This allows plugins to access chunks slightly outside of the
max world border (such as ones which may be loaded naturally
by players) without tripping any logs.
This method was used pre 1.17 era where an Entity was explicitly
tied to a (then called) Chunk's entity slices. If an entity
was not inside a Chunk, then it was considered invalid as
it was not possible to save the entity.
In 1.17+, entities are now tied to a separately tracked entity
section management system. This system is far more reliable now
as it no longer requires a full chunk load to properly track
entities for saving. As a result, an Entity if inside the world
is always attached to some entity chunk section (except in rare
cases in Vanilla which are fixed in Moonrise).
As a result, whether the chunk the entity is in is loaded is no
longer an indication of whether they are tracked in the world
and we can reliably infer that the entity is correctly in the
world through the valid field alone.
Additionally drop the isInWorld() check, as valid=true implies
isInWorld=true. More importantly, the isInWorld() check invokes
getHandle which may trip a thread check on Folia. This will fix
World#getEntities() and friends exploding on Folia.
However, World#getEntities() on Folia still cannot reliably return
all entities in the world as actions such as cross-region
(not cross-world) teleporting will remove entities from the world.
This allows the watchdog thread to be seen as the
primary thread during shutdown, which prevents it
from tripping thread checks in various areas.

The windows file system does not write metadata unless
the FileChannel is explicitly flushed with metaData=true.
Note: Setting SYNC (not DSYNC) on the FileChannel does not appear
to write the metadata.
Specifically, we are interested in writing the last modified
timestamp so that fs watchers can detect when RegionFiles are
modified.
