Pool LZMA workspaces and streamline 7z metadata writing
...
Reuse LZMA2 trial decoders and pooled compressed output, pool and consolidate decoder probability banks, lazily rent encoder optimization scratch, and avoid copying direct async memory writes.
Use bounded stack scratch and stream 7z metadata without temporary property buffers. Add ownership, failure, context-shrink, Unicode, and block-boundary regressions.
Document allocation profiles, the small-file LZMA2 throughput tradeoff, and rejection of exact-size match-finder arrays. Validation: 3,016 .NET 10 tests passed; all library targets, net48 tests, and performance project compile; formatting checks pass.

Reduce 7z copy and LZMA decoder allocations
...
Pool writer CRC-copy buffers, use memory-based async read overloads on modern targets, reuse LZMA2 decoders across resets, and initialize probability-model banks lazily.
Add reset/property-change, memory-read, writer boundary/CRC, and growth regression coverage. Document staged profiling results and rejection of dictionary-growth policies that regress small-file allocations.
Validation: 2,997 .NET 10 Release tests passed, all library targets built, net48 tests compiled, and formatting checks passed.

Release pooled 7z decoder buffers across async and partial reads
...
Dispose cached folder decoders during async archive cleanup and scope temporary encoded-header decoders in both read paths. Release LZMA range-decoder input buffers on partial reads and failures while preserving borrowed source ownership.
Correct the synchronous extraction-reader benchmark and expand lifetime and checksum coverage. Document profiling showing async Archive allocations falling from 8.95 MiB to 0.70 MiB per extraction, with metadata-only allocations reduced by 70%.
Validation: 2,989 .NET 10 Release tests passed; all library targets, the performance project, and net48 test compilation succeeded. Formatting and whitespace checks passed.
