Use release events to trigger builds from automated weekly releases

GitHub Actions tokens cannot trigger workflows on tag creation (security feature).
This change replaces git tag + push with gh release create, which triggers release
events that CAN activate workflows.

Changes:
- scheduled-releases.yml: Use gh release create instead of git tag + push
- build.yml: Add release: types: [published] trigger with weekly-only filter

The filter ensures only automated weekly releases trigger builds, blocking manual
releases until needed
