Overview

Wraps OHOS's binary-sign-tool to apply -selfSign 1 to a freshly built shared library. Mandatory for runtime loading on production OHOS devices; dockerharmony skips this check (dev container).

Design: #sign_command is a pure-data accessor returning the argv that #sign would run. Specs assert on the command shape without actually invoking the tool -- no doubles needed.
