Subject: [PATCH] fix: make reset-version portable across BSD and GNU sed

sed -i -E on macOS was broken because BSD sed's -i requires an
explicit backup-suffix argument, so it consumed -E as that suffix
instead of enabling extended regex. This left capture groups
undefined, causing "\1 not defined in the RE". Detect the OS via
uname and pick the correct in-place sed invocation, and drop a
stray space in the replacement that produced version = " 0.0.1".
