+- **macOS DMG release artifacts** — `darwin/amd64` and `darwin/arm64` DMGs are now published to every GitHub release alongside the existing tarballs. Each DMG includes the binary, `README.md`, `deepdiffdb.config.yaml.example`, and an `install.sh` helper that copies the binary to `/usr/local/bin`.
+- **Windows installer release artifact** — A native NSIS installer (`deepdiff-db-vX.Y.Z-windows-amd64-installer.exe`) is published to every GitHub release. It installs `deepdiffdb.exe` to `%ProgramFiles%\DeepDiffDB`, adds that directory to the system PATH (idempotent, no reboot required), registers the app in Add/Remove Programs, and includes a full uninstaller.
