- EdzArchive checks the archive magic up front: gives a clear message for
zip-format .edz (not yet supported) and unrecognised data, instead of an
opaque 7z decode error.
- Trim the vendored LZMA SDK headers to the decode closure actually used
(removes 21 unused encoder/multithread/Xz/Aes headers; 18 .c + 18 .h remain).
- Add sources/import/edz/README.md documenting the feature, the data mapping
and the bundled SDK.
