SopLib 1.0.1

• Added MiniMessage <center>...</center> support in the shared text pipeline.
• Added shifted centering support:
  • <center-10>...</center>
  • <center+10>...</center>
• Added public MiniMessage preprocessing through TextUtils.prepareMiniMessage(...).
• Shared MiniMessage-aware plugins can now use SopLib for common preprocessing instead of implementing their own local parsing logic.
• Updated documentation with centered MiniMessage examples.
