Rene Cannao	e9abee625b	fix: Execute prepared statement in execute_parameterized_query ... The execute_parameterized_query function in RAG_Tool_Handler was creating a prepared statement and binding parameters, but then executing the raw query string instead of the prepared statement. This completely bypassed the parameter binding, making the function useless for preventing SQL injection. Changed to use vector_db->execute_prepared(stmt, ...) to execute the bound statement instead of the raw query, so the bound parameters are actually used.
