The escapeStringLiteral function was outputting just `\'` for embedded single quotes, but ClickHouse EXPLAIN AST uses `\\\'` (escaped backslash + escaped quote) for embedded quotes within string literals. This fix aligns with the behavior shown in many existing tests: - 00011_sorting: DateTime(\'Asia/Dubai\') - 00324_hashing_enums: Enum8(\'Hello\' = 0, \'World\' = 1) - 00471_sql_style_quoting: hello\'world - And many others Also fixes test 03404's explain.txt which had incorrect escaping. Enables 4 previously failing tests: - 01434_netloc_fuzz - 03003_sql_json_nonsense - 03521_tuple_of_dynamic_with_string_comparison - 03567_finalize_write_buffer_valid_utf8
