add AOT smoke and missing tests

[adamhathcock]

This pull request introduces comprehensive support for testing and validating Ahead-Of-Time (AOT) compilation and async parity in the SharpCompress library. The most significant changes include adding a new AOT smoke test project with its dependencies, updating the CI workflow to run the AOT test, and introducing thorough tests for async/sync parity and cancellation handling. Additionally, several improvements and corrections are made to the performance benchmarks to use the updated APIs.

AOT Compilation and Testing:

• Added a new project SharpCompress.AotSmoke targeting .NET 10.0, configured for AOT and trimming, with a smoke test that verifies basic archive creation and extraction using SharpCompress. [1] [2]
• Added a packages.lock.json file to lock dependencies for the AOT smoke test, ensuring reproducible builds and correct package versions.
• Updated the GitHub Actions workflow to build, publish, and execute the AOT smoke test on Ubuntu, ensuring AOT compatibility in CI.

Async Parity and Cancellation Testing:

• Introduced a new test class AsyncParityAndCancellationTests (enabled for .NET 8.0+) that verifies async/sync entry enumeration parity, proper cancellation behavior before and during extraction, and correct stream disposal semantics for both archive and reader APIs.

Performance Benchmark Improvements:

• Updated TarBenchmarks to use the unified ArchiveFactory and ReaderFactory APIs, corrected stream usage, and ensured the correct compression provider registry is used for benchmarks involving GZip-compressed tar files. [1] [2] [3] [4] [5]

Pull request overview

This PR adds an AOT smoke-test executable and expands test coverage around async/sync parity and cancellation behavior, plus aligns some performance benchmarks with the newer factory APIs and compression provider registry usage.

Changes:

• Added SharpCompress.AotSmoke (net10.0) to validate trimming + NativeAOT publish/run in CI.
• Added AsyncParityAndCancellationTests to assert async/sync entry parity, cancellation behavior, and stream disposal semantics.
• Updated TAR benchmarks to use ArchiveFactory and the default compression provider registry when benchmarking System.IO.Compression GZip.
