Summary

Ensure the parent directory of the ASP.NET development certificate export path exists before running dotnet dev-certs https -ep ... -p ....

This prevents SSL-enabled .NET container debugging from failing with exit code 3 on hosts where the certificate export directory has not yet been created. Existing directories are left unchanged, and directory creation failures propagate normally.

Fixes #640.

Validation

• Container Tools lint and build passed.
• Exercised missing and existing export directories and confirmed directory creation errors prevent certificate export.
• Reproduced the original failure locally: certificate trust succeeded, but export returned code 3 because %APPDATA%\ASP.NET\Https did not exist.
