…ds for improved logging

…tive AOT prep

* add RequiresDynamicCode / RequiresUnreferencedCode and DynamicallyAccessedMembers
  attributes to Session, SessionReflection, and AwsClientFactoryWrapper
* embed ILLink.Descriptors.xml in LocalStack.Client.Extensions to preserve
  ClientFactory<T> private members
* update README with “Native AOT & Trimming Status” notice, link to draft‑PR #49,
  and clarify that v2.0.0 GA ships without Native AOT support

…rimming descriptors

…inability

…emove transitive props file

…fy README for AOT compatibility instructions; adjust BuildContext for versioning format

- Fix versioning bug preventing package deployment by switching from build metadata format (2.0.0+date.sha) to pre-release format (2.0.0-nightly.date.sha) for NuGet filename compatibility
- Eliminate duplicate CI/CD runs by removing feature/* branches from push triggers and implementing PR-driven deployments for feature branches
- Update GitHub Actions workflow branch name detection using conditional expressions for both push and pull_request events
- Ensure proper SemVer 2.0 compliance where feature branch packages (2.0.0-source-generator-*) rank higher than nightly builds (2.0.0-nightly.*) due to lexicographic ordering
- Maintain backward compatibility with existing versioning strategy while enabling reliable automated package publishing

Affects packages:
- LocalStack.Client
- LocalStack.Client.Extensions
