Get-RsaPublicKeyInfo currently compiles its embedded SevenTiny C# at
runtime via `Add-Type -Language CSharp`. That works fine under stock
pwsh, but in any host that embeds PowerShell as a library (Azure
Functions custom-handler images, embedded SDK hosts, etc.) `$PSHOME`
resolves to the host directory and Roslyn can't find its reference
assemblies — Add-Type throws DirectoryNotFoundException and every
Read-DkimRecord call silently returns empty records.
This commit extracts the C# into Source/SevenTinyRsa/SevenTinyRsa.csproj
and bundles the precompiled SevenTinyRsa.dll alongside the manifest.
DNSHealth.psd1's new RequiredAssemblies entry preloads the type before
the .psm1 runs; Get-RsaPublicKeyInfo's existing
`if (!('SevenTiny.Bantina.Security.RSACommon' -as [type]))` guard then
short-circuits, so the runtime Add-Type fallback stays in place
untouched for any host that doesn't ship the DLL.
Behaviour on a normal pwsh import is unchanged — the type just resolves
to the bundled assembly instead of going through the compile step.
Read-DkimRecord starts working on embedded-PS hosts where it previously
failed silently.
Build pipeline: dotnet build Source/SevenTinyRsa/SevenTinyRsa.csproj
-c Release -o DNSHealth/. build.psd1's CopyDirectories now includes
SevenTinyRsa.dll so Build-Module carries it into Output/DNSHealth/.
