Subject: [PATCH] fix: correct JSON parsing for prerelease detection in GitHub
 API response

The GitHub API returns "prerelease": false (with space after colon), but
the grep pattern used "prerelease":false (no space). Also, tag_name and
prerelease are on different lines after tr '{' '\\n', so the piped grep
chain couldn't find both fields. Fixed with grep -B5 to look backwards
from prerelease line to find tag_name.
