Fix Zapstore publish workflow flag handling

[AnthonyRonning]

Summary

• replace the removed �[1m-y�[0m flag with �[1m--quiet�[0m in the Zapstore publish workflow
• fail the workflow if �[1mzsp�[0m prints usage text or an unknown-flag error while still exiting successfully
• preserve normal success and no-op cases for Zapstore publishes

Validation

• git diff --check
• prettier --check .github/workflows/zapstore-publish.yml
• simulated the workflow shell logic for help-text false-success, success, no-op, and failure cases
• pre-commit hook: frontend build and tests
