- Add MIT LICENSE (Thorsten Buss) with attribution to the upstream
MIT-licensed greyshirtguy/ProPresenter7-Proto definitions.
- Add comprehensive README.md: badges, feature matrix, install,
seven runnable getting-started examples (read/modify/generate
songs, playlists, bundles, global libraries), CLI tool reference,
documentation index, project structure, caveats.
- Update composer.json with package name (bussnet/propresenter7-php-api),
MIT license, keywords, author, homepage, support URLs, dev autoload,
and a `composer test` script.
- Polish doc/INDEX.md, doc/keywords.md, and doc/CONTRIBUTING.md so they
read well for both humans and AI assistants; remove README-duplicate
content from INDEX.md and link to the top-level README instead.
- Expand .gitignore to cover IDE/OS metadata and agent workspaces.
All 370 tests still pass (9,200 assertions). README examples #3 and #5
verified end-to-end (generate -> read back -> assert metadata).
