- Extracted the chromiumCanLaunch probe from browser-tab-evaluate into a
shared test/tools/chromium-probe.ts helper.
- The two attached-navigation tests from PR #7006 launch real headless
Chrome; CI runners without Chrome system libraries (libnspr4 & co.)
cannot exec the downloaded binary, failing the native/unit bucket.
- Gave both tests 30s timeouts to survive CI cold starts.
- Removed the once wrapper from Puppeteer's request emitter on first fire so it cannot leak into later runs.
- Added regression coverage asserting a fired once handler leaves zero residual request listeners.
Fixes#6004
- Removed run-scoped Puppeteer request handlers and disabled interception on every browser.run exit path.
- Recycled workers when bounded interception cleanup cannot restore the tab, with raw CDP recovery for held requests.
- Added live Chromium coverage for held requests, normal traffic restoration, and thrown setup calls.
Fixes#6004
- Exported ensureChromiumExecutable so the test can probe launchability.
- CI runner holds the downloaded Chrome but lacks libnspr4 & co., so the
binary fails at dynamic-link time; probe --version and skipIf instead
of failing the release run.
