fix!: add complete input to history, including continued input

this introduces a breaking change to runner functions.
they are now required to return 3 values, the first
being the user's input, and the 2 others that it was
before. the `hilbish.runner` functions respectively
have been updated, so if you just return from those
there will be no difference

+A runner function is expected to return 3 values: the input, exit code, and an error.
+The input return is there incase you need to prompt for more input.
+If you don't, just return the input passed to the runner function.
 The exit code has to be a number, it will be 0 otherwise and the error can be
 `nil` to indicate no error.
