Bug Fixes

• Fix PB4 (Fabric Text Placeholder API) placeholders not resolving on MC 1.20.1. Two root causes: (1) the resolver picked the wrong parseText overload (TextNode instead of Text), and (2) it looked up the text factory by the Yarn name literal, which does not exist in the intermediary namespace the addon runs in. Both are now resolved via shape-based reflection that is mapping-namespace agnostic. Verified against the real intermediary runtime classpath.

This completes the PB4 fix started in 2.1.1.
