Use where on Windows to detect devcontainer cli - #130
Conversation
On Windows, the `which` command is not available, which prevents detection of the devcontainer CLI. This updates `checkDevcontainerCli` to use `where` instead of `which` when `process.platform === 'win32'`. Co-authored-by: athal7 <467872+athal7@users.noreply.github.com>

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Assert the selected command, not only the return type.
These tests pass regardless of whether checkDevcontainerCli() invokes where or which, so they would not catch the regression this PR targets. Intercept the process-command boundary and assert where for win32 and which for linux/darwin, while retaining the cleanup.

Updates checkDevcontainerCli to accept a platform parameter (defaulting to process.platform) so it can be cleanly tested. Also, the tests now verify that if 'where' command throws ENOENT on non-Windows platforms (like Linux CI), the error is gracefully caught and checkDevcontainerCli still returns a boolean without throwing an unhandled exception.

This change resolves an issue on Windows where the
devcontainerCLI is never detected becausewhichis not supported on Windows. By checkingprocess.platform === 'win32', we now correctly usewhereinstead ofwhichfor executable existence detection on Windows systems. Unit tests have also been added/updated to verify this behavior across platforms.Fixes #123
