[BuildWu19940706]

Summary

• remove three invalid shell: zsh declarations from the development preview workflow
• use the GitHub Actions default Bash shell for the inline steps

Root cause

The v0.1.1 tag workflow failed during “Validate tag version” before tests or packaging ran. GitHub Actions accepts built-in shell names such as bash, or custom shell format strings containing {0}; plain zsh is rejected as an invalid shell option.

Impact

The inline commands are Bash-compatible, while package_release.sh still invokes its own zsh shebang. Future version tags can pass validation and proceed through testing, Universal packaging, checksum verification, and pre-release creation.

Validation

• failing run: https://github.com/BuildWu19940706/MacAppLock/actions/runs/29812329745
• workflow YAML parsing passed
• tag/version validation passed under Bash for v0.1.1
• git diff --check passed
