Pull request overview

This PR adds a categorical_limit parameter to the TabularSummary class to limit the number of unique values stored for categorical columns. This is useful for columns with high cardinality where tracking all unique values would be memory-intensive.

Key changes:

• Added categorical_limit parameter to control the maximum number of unique categorical values stored per column
• Introduced categorical_counts tracking to maintain statistics even for columns that exceed the limit
• Updated summary output to include categorical counts and the limit value
