After moving Gemfile/Gemfile.lock to fastlane/, the - Gemfile / - Gemfile.lock entries in _config.yml's exclude list are no-ops; the parent fastlane exclude already covers everything inside.
.gitignore picks up _site/, .jekyll-cache/, vendor/bundle/ so local Jekyll runs don't leave tracked artifacts.
This commit updates the Jekyll configuration file (`_config.yml`) to:
- Include `README.md` and `CHANGELOG.md` in the site build.
- Exclude `CONTRIBUTING.md` and `CLAUDE.md` from the site build.
This commit updates the Jekyll configuration to include `jekyll-github-metadata` and `jemoji` plugins. It also introduces a `CHANGELOG.md` file that automatically generates a formatted changelog page from GitHub releases. The default changelog text for new app versions in Fastlane has also been updated to be more engaging and directly link to the new changelog page.
