### Added
- `tools/update_github_releases.py`: one-shot script to sync GitHub Release bodies via API using local `tools/release-notes/` snippets

### Fixed
- Linux overlay shims (`tools/linux/overlay/include/`) now use `#include_next` instead of `#include` to forward to the real MinGW system header, avoiding infinite preprocessor recursion on Linux/WSL (GCC 12+)
- Removed stale prebuilt `plugins/*/nsis7z.dll` binaries from the repository
