* test(reset): probe Bash variable expansion on Windows
Use a bounded variable-expansion probe so a launcher that starts successfully but consumes $x is rejected. Rebase over #676 and keep its upstream-checkout guard alongside Bash discovery.
Thanks to MadsLorentzen for diagnosing the launcher expansion failure and verifying the stronger probe.
* changelog: place the #671 entry under [Unreleased]
