Subject: [PATCH] fix(validation): suppress ANSI color in bundling-failure
 annotation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

GitHub Actions sets GITHUB_ACTIONS unconditionally, which redocly's color
library treats as reason enough to force color even on captured (non-TTY)
output. The resulting trailing color-reset line clobbered the
${err##*$'\n'} extraction, showing only "[39m" instead of the real message
— verified against a real runner, not local simulation.
