Subject: [PATCH] fix: print KSorobanError message to stderr before exit

When `_exec_test` catches a KSorobanError (e.g. 'Unsupported SC value
type'), it exits with code 1 but prints nothing, leaving the user with
no indication of what went wrong.

Print the error message to stderr before exiting.

Closes #92
