* Initial plan
* Fix IsSolidAsync() returning false for 7z solid archives
SevenZipArchive was missing an override for IsSolidAsync(), so the
base class default (always returning false) was used. Added an override
that uses the same logic as the sync IsSolid property: load entries
asynchronously and check if any folder has more than one file.
Also updated existing async tests to use IsSolidAsync() instead of
casting to SevenZipArchive to call the sync IsSolid, and added a new
SevenZipArchive_TestSolidDetectionAsync test that mirrors the existing
sync SevenZipArchive_TestSolidDetection test.

- Implemented ReadAsync and RefillCacheAsync methods in BufferedSubStream
- Added async test cases for SevenZipArchive (LZMA, LZMA2, Solid, BZip2, PPMd)
- Tests show LZMA, BZip2, and PPMd working correctly
- LZMA2 and Solid archives still failing with Data Error - investigating cache state management
