fix: disable electron-builder auto-publish to prevent 403 errors

- Add publish: null to build config to prevent automatic release creation
- Set PUBLISH=never environment variable in workflow
- Add contents: read permission to build jobs
- Let release job handle all release creation instead of electron-builder
