Missing Input Validation for `indent_count` in `SqlToStringFormat`

[pankaj-bind]

The SqlToStringFormat class in pylegend/core/databse/sql_to_string/config.py does not validate the indent_count parameter in its constructor. Allowing a negative indent_count can lead to unexpected formatting behavior and bugs.

Hi @pankaj-bind , I’ve implemented validation for indent_count in SqlToStringFormat (raise ValueError for negatives) and added unit tests (valid/invalid values, push_indent, separator). I’ll open a PR referencing this issue. Please let me know if you’d prefer clamping/coercion instead of fail-fast.
