fix(cli): address review findings — exit codes, missing inputs, null safety

- Add process.exit(1) in cli.ts catch block so failures produce non-zero exit codes
- Add 6 missing build inputs: containerRegistryRepository, containerRegistryImageVersion,
  dockerIsolationMode, sshPublicKeysDirectoryPath, cacheUnityInstallationOnMac, unityHubVersionOnMac
- Add 6 missing orchestrate inputs: kubeStorageClass, readInputFromOverrideList,
  readInputOverrideCommand, postBuildSteps, preBuildSteps, customJob
- Fix activate command description to accurately reflect verification behavior
- Add null check before accessing result.BuildResults in orchestrate handler
