fix: add proper conditions to docs-deploy workflow and update Go component configuration

- Add branch protection to docs-deploy workflow (only runs on main branch)
- Add secret validation with graceful fallback when secrets are not configured
- Update Go component WIT world configuration to use standard WASI CLI interface
- Fix calculator WIT file to properly expose add and subtract functions

This resolves the CI workflow issues that were preventing proper validation.
