f63cd81a65 Reduce allocations in encrypted RAR reading 
Reuse bounded buffers and transform AES blocks in place. Remove per-block arrays and plaintext queues, avoid per-byte header allocations, and dispose owned crypto transforms.

Add encrypted RAR benchmarks, regression tests, and before/after profiling results. Full .NET 10 suite passes (2,446 tests); all library targets build and net48 tests compile.

e61a335d54 Reduce allocations in RAR5 password key derivation 
Reuse keyed HMAC state and digest buffers on modern .NET targets while preserving RAR5's three PBKDF2 snapshots. Add independent derivation checks and an allocation regression test.

Profiling on macOS ARM64 with .NET 10 reduced allocations by 99.96%, but showed slower throughput; Alpine-specific timing remains unverified. Full .NET 10 test suite passes.

eac609b35a Report truncated encrypted RAR data as InvalidFormatException asynchronously 
ReadExactAsync throws IncompleteArchiveException, so the async decrypt
path's EndOfStreamException catch never ran. On net48, EntryStream.Dispose
skips the entry through the async path, so its IncompleteArchiveException
replaced the InvalidFormatException from the synchronous read and failed
Rar_Multi_Reader_Encrypted. Sync and async now report truncated encrypted
data as InvalidFormatException.

830c816269 Fix net48 test build: use plain using for types without DisposeAsync 
AsyncOnlyStream and EntryStream have no DisposeAsync on net48, so
await using fails to compile for that target.

bc58792b86 Fix encrypted RAR header state when rescanning archives 
Reset scan-specific encryption state in sync and async header readers while retaining the KDF cache. Add RAR4/RAR5 rescan and solid encrypted extraction regression coverage.

Fixes #1422
