- Introduced `prepare.js` to validate PR mergeability and branch targeting.
- Added `reviews.js` for automated review dismissal and posting.
- Created `run` script to execute actions with GitHub context.
- Implemented rate limiting in `withRateLimit.js` to manage API requests.
- Added `supportedBranches.js` for branch classification logic.
- Created `update-pinned.sh` for updating pinned dependencies.
- Added `pinned.json` to manage pinned Nix dependencies.
- Updated `libnbtplusplus` version from 2.3 to 3.0 and adjusted README accordingly.
