The SSH mount attempts to support both Unix (HOME) and Windows (USERPROFILE) by concatenating environment variables. However, if both variables are set (which can happen on Windows with Git Bash or WSL), this will concatenate both paths creating an invalid path. A more robust approach would be to use conditional mounting or test this configuration on both platforms to ensure it works as intended.

Suggested change

	"source=${localEnv:HOME}${localEnv:USERPROFILE}/.ssh,target=/home/vscode/.ssh,type=bind,consistency=cached"
	"source=${localEnv:HOME}/.ssh,target=/home/vscode/.ssh,type=bind,consistency=cached"

I'll just use the UNIX-compliant path.

The container name uses an underscore ("py_cppmodel Dev Container") while the project name in pyproject.toml uses a hyphen ("py-cppmodel"). For consistency with the project naming conventions, consider using "py-cppmodel Dev Container" instead.
