cc-triage's featureless gate (#2267): a changelog bullet that matches this regex routes the
snapshot to LLM extraction; if NO bullet matches, the version graduates as
featureless with no LLM call. The 2.1.173 trap: passive
"…when sandbox was enabled in settings" tripped enabl\w*, the LLM
correctly returned an empty array, and the M134 guard sentineled parse_failed
on every retry. The negative lookbehind below excludes was/is/are/were/been + "enabl*".
