BREAKING CHANGE: Promote beta features to stable release for v5.0.0
This commit ensures the stable release gets properly published to NPM and GitHub releases.
- Add contents:write permission for GitHub Actions
- Configure git to use GITHUB_TOKEN for authentication
- Set remote URL with access token for push operations
- This should resolve the 403 permission denied error
- Add GitHub Actions workflow for one-click promotion to stable
- Supports patch/minor/major version bumps
- Automatically merges main to stable and handles version updates
- Eliminates manual git operations for stable releases
- Configure semantic-release for @beta and @latest tags
- Main branch publishes to @beta (bleeding edge)
- Stable branch publishes to @latest (production)
- Enable CI/CD workflow for both branches
- Update release workflow Node.js version from 18 to 20 to match package.json requirements
- Remove push trigger from Discord workflow to reduce notification spam
This should resolve the semantic-release content-length header error after org migration.
