Audited batch 5 components (ChargedProjectiles, BundleContents, Container,
WritableBookContent, BlockState, PotDecorations) against official 1.20.6
decompiled STREAM_CODEC definitions. All network encodings were correct.
Removed redundant NumberOfItems/NumberOfPages/NumberOfProperties fields from
ContainerComponent, WritableBlookContentComponent, BlockStateComponent, and
PotDecorationsComponent. Serialize now uses the actual collection .Count
instead of a potentially stale cached value, matching the pattern already
used by ContainerComponent's Serialize and other components.
Also modernized loop style (foreach with deconstruction where applicable)
and fixed a typo in an exception message ("setialize" -> "serialize").
Made-with: Cursor
