Replace lowercase primary constructor parameter references (dataTypes.,
subComponentRegistry., itemPalette.) with PascalCase base class property
references (DataTypes., SubComponentRegistry., ItemPalette.) in method
bodies of all StructuredComponent and SubComponent subclasses.
This eliminates CS9107 warnings where subclass primary constructor
parameters shadow the base class properties they are assigned to.

Audited all 8 high-complexity structured components against official 1.20.6
decompiled STREAM_CODEC definitions. Found and fixed bugs in 3 components
plus a systemic NBT serialization issue:
TrimComponent (ID 35):
- Serialize had TrimPatternType and ShowInTooltip incorrectly nested inside
the TrimMaterialType==0 branch; moved them outside to match Parse logic
- Description fields (TrimMaterial.description, TrimPattern.description) were
read/written as String but official codec uses ComponentSerialization
(NBT Tag format); changed to ReadNextNbt/GetNbt
ProfileComponent (ID 46):
- Serialize was missing the HasUniqueId Bool prefix before UUID
- Serialize only wrote properties when count > 0 but omitted the VarInt count
prefix entirely when empty; now always writes VarInt count
WrittenBookContentComponent (ID 34):
- Page content uses Filterable<Component> where Component is NBT-encoded via
ComponentSerialization.STREAM_CODEC, not plain String; changed Parse to use
ReadNextNbt and Serialize to use GetNbt
- Added RawContentNbt/FilteredContentNbt fields to BookPage record for
round-trip NBT preservation
- Removed unnecessary ChatParser.ParseText on title (it's a plain string)
DataTypes.GetNbt:
- Added TAG_String root support for 1.20.4+ (chat components like "Page 1"
are encoded as TAG_String, not TAG_Compound)
- Fixed root name handling: versions >= 1.20.2 omit the root compound name,
but GetNbt was unconditionally writing it
Components confirmed correct (no changes needed):
- FoodComponentComponent (ID 20), ToolComponent (ID 22),
InstrumentComponent (ID 40), PotionContentsComponent (ID 31),
AttributeModifiersComponent (ID 12)
