023 router fmt blk response body

// PINS: fmt.blk HTML returned as an orisha Response body, then freed
// after the bytes have been used. 350_022 prints inside the router arm
// and continuation_codegen frees there. Ward's GET / `return`s the slice
// (`body: f`); freeing in the arm is use-after-free, and not freeing is
// a leak. `body_allocated` rides the Response; `orisha:release-body`
// discharges it after `answer` (the same seam `serve` uses after reply).
