ci: simplify Mac workflow by removing Node.js dependency

Remove the dependency on Node.js CI job for Mac and iOS builds, and
always build web artifacts locally in the Mac workflow. This simplifies
the CI pipeline and removes the artifact download step that could fail.

Changes:
- Remove `node` dependency from `mac` and `ios` jobs in ci.yml
- Replace artifact download with direct web build in mac.yml
- Simplify the build process by removing conditional logic

This extracts the CI workflow improvements from PR #318.
