feat: handle test:interrupted event (#172)

MoLow · claude · web-flow · commit 79f71f483f5f · 2026-04-16T14:32:08.000+03:00
Align with nodejs/node#61676 which adds a `test:interrupted` event emitted on SIGINT. This shows which tests were running when the process was interrupted. - gh: display yellow "Interrupted while running:" section with test names and locations, closing any open GitHub Actions group - github: emit `::warning::` annotations for each interrupted test Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
