When using IAM authentication for RDS, the token expires after ~15 minutes. The sql_select processor now detects connection failures (driver.ErrBadConn) and automatically reconnects with a fresh IAM token, then retries the query. Changes: - Store driver, dsn, and connSettings on struct for reconnection - Add reconnect() method that closes old connection and establishes new one - Detect driver.ErrBadConn in ProcessBatch and trigger reconnection - Retry failed query after successful reconnection Related to: warpstreamlabs#469

THIS IS NOT TO BE MERGED YET. the fix was "vibed" and havent been tested yet. it seems like the above fix on #469 only apply to partial sql methods. not sure if this is the right way to add the reconnect mechanism. so treat this contribute as a proposal for a fix.
