fix: Reader error loop from (= nil 27), Swank *standard-output* redirect

Browse Source 
- Remove 'code' variable binding (redundant with b). esc-seq now
  starts with (and b (= b 27) ...) so when b is nil (timeout), the
  and short-circuits before (= b 27) can error with 'NIL is not
  of the type NUMBER'.
- Swank prints to *standard-output*, not *error-output*. Bind both
  to string output streams to prevent ';; Swank started' leak.
