ci: use readable action versions

[smiggleworth]

Summary

• use readable action refs in CI and publication
• name and format the post-publication registry smoke-test steps
• inherit the shared publisher environment through ci: use readable action refs and npm environment actions#15
• keep every workflow step explicitly named with consistent whitespace
• use boolean wrap props in SPA and startkit templates so packed projects type-check against current Askr packages

Validation

• actionlint .github/workflows/*.yml
• npm run check
• npm run test:templates
• red: packed SPA template failed with TS2322 for string wrap props
• green: focused SPA/startkit and all packed-template checks pass
• zero SHA-pinned action refs and zero unnamed workflow steps
