Summary

  • Fix CQL engine not wrapping indexed collection columns (List, Set, Map) in frozen<...>
  • Without this fix, creating a table with indexed collection columns produces invalid CQL
  • Adds unit tests for indexed collection column freezing

Test plan

  • Unit tests added for List, Set, and Map columns with and without indices
  • Manual verification that column definitions now include frozen<...> wrapper

Fixes #162

Fix indexed collection columns not being frozen in table definition
c6eeb32 
When creating a model with indexed collection columns (List, Set, Map),
the CQL engine now properly wraps the collection type in frozen<...>.

This fixes the issue where creating a table with indexed collection
columns would produce invalid CQL without the frozen wrapper, leading
to errors when trying to create the index.

Fixes #162
