URL: https://github.com/apache/paimon-mosaic/pull/24

   ## Problem
   
   Schema block layout changed while the file footer version stayed at v1. 
Existing v1 files can be parsed with the new layout, causing the legacy logical 
index to be read as a type header and potentially corrupting schema metadata 
silently.
   
   ## Fix
   
   Bump the current file version to v2 and keep v1 as the legacy format. Route 
schema deserialization by footer version, parse v1 with the legacy 
logical-index layout, and add a v2 schema layout marker for the current format.
   
   Also add regression coverage for legacy v1 schema decoding.
