BruceChen a36ba23ba6 fix: StructuredComponents batch 1 audit — TrimComponent, ProfileComponent, WrittenBookContent, and NBT serialization
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)
