[WIP] Fix Battlestation::CLI#run to return 0 when exitstatus is nil

[Copilot]

Thanks for asking me to work on this. I will get started on it and keep this PR's description up to date as I form a plan and make progress.

Original prompt

The test for Battlestation::CLI#run in spec/battlestation/cli_spec.rb fails because the method returns $?.exitstatus, which is nil when no child process has been run in the test context. The spec expects subject.run to return 0. To fix this, update the implementation in lib/battlestation/cli.rb to return 0 if $?.exitstatus is nil. Update line 50 to:

return $?.exitstatus || 0

This ensures the method returns 0 in the test context and passes the expectation.

I asked Copilot to fix a CI error on #37 but it opened this PR against the master branch when I need to make the change on the branch of #37.
