20932b81b5 Fix SevenZipArchive.IsSolidAsync() always returning false (#1284) 
* 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.

265d99095b Fix three BLAKE2sp correctness bugs and eliminate allocations in hot path 
1. Fix off-by-one in Update(BLAKE2SP): pos was masked with 448 (64×7)
   instead of 511 (64×8−1), causing incorrect leaf assignment when update
   chunks are not multiples of 64 bytes. This produced wrong hashes
   whenever streaming reads didn't align to 64-byte boundaries.

2. Fix double-finalization when Read() is called again after returning 0.
   Final() was called unconditionally on each EOF read, re-running
   compression on an already-finalized state and corrupting the hash.
   EnsureHash() guards with a null-check and is idempotent; both sync
   and async Read paths share the fix. _blake2sp is set to null after
   finalization so any erroneous post-final calls fail fast rather than
   silently corrupting state.

3. Fix false-positive CRC check when stream is not fully drained.
   _hash was initialized to fileHeader.FileCrc in the constructor, so
   GetCrc() returned the expected CRC rather than the computed one if
   the stream was abandoned early. The check would then compare the
   expected hash against itself and always succeed, silently accepting
   a corrupt or incomplete file. _hash is now null until the stream is
   fully read; GetCrc() throws if called early rather than returning a
   misleading value.

Additional changes:
- Compress: stackalloc m/v arrays instead of heap; LE fast path via
  MemoryMarshal.Cast replaces 16 BitConverter.ToUInt32 calls per block
- Final(BLAKE2S): write directly to Span<byte>, eliminating MemoryStream
  and BitConverter.GetBytes allocations; 8 leaf digests now stackalloc'd
- Inner classes and fields: private, sealed, readonly where applicable
