Bug Fixes

• Fix Fabric Text Placeholder API (PB4) not resolving placeholders on MC 1.20.1. The resolver now derives Minecraft classes from PB4 method signatures instead of hardcoded Yarn-mapped class names.
• Fix %player_displayname% built-in placeholder now resolves the actual player display name (from the platform player object) instead of falling back to the raw username.

Improvements

• Added diagnostic logging for resolver selection and PB4 integration status.
