2.66.2

(chore): Patch C# SDK generator container CVEs flagged in the AWS ECR / grype scan. Switch the apk upgrade to pick up the latest Alpine 3.23 patches (nghttp2, openssl, libcrypto, libssl, sqlite-libs, expat, etc.), pin a non-vulnerable set of System.* NuGet dependencies, drop the bundled PowerShell warmup so its vendored System.Net.Http 4.3.0 / System.Security.Cryptography.Xml DLLs are no longer included in the published image, and clear the System.Net.Http 4.3.0 artifact the /dependencies.csproj warmup leaves in the NuGet cache after restore.
