Fix JSON function error handling when called from DuckDB engine#139
Merged

When JSON functions (json_overlaps, json_depth, json_unquote) are called from DuckDB engine with invalid input, they previously triggered MySQL error handling (my_error) which is not appropriate in the DuckDB context. This fix adds a `m_caller_is_duckdb` flag to the relevant JSON function classes so that when called from DuckDB, errors are thrown as C++ exceptions (duckdb::InvalidInputException) instead of MySQL errors, allowing DuckDB to handle them properly. Fixes alibaba#136 Co-Authored-By: Claude Opus 4.6 <[email protected]>
