v1.42.0

What's Changed

• chore: sync version 1.41.0 to staging by @rapiercraft-forgedock[bot] in #4940
• review-staging summary blocks on the gate-marker check, which echoes its own earlier GATE_FAILURE (release loop) (#4941) by @rapiercraft-forgedock[bot] in #4942
• feat(selftest): live contract harness — real gh/git/pool lifecycle against a sandbox repo, required before the release review (#4865) by @rapiercraft-forgedock[bot] in #4944
• feat(selftest): nightly live selftest through the schedd timer (follow-up to #4865) (#4894) by @rapiercraft-forgedock[bot] in #4945
• fix(review-staging): selftest release gate only when selftest.sandbox_repo is set by @rapiercraft-forgedock[bot] in #4947
• fix(selftest): release-review fixes — trusted markers, detached nightly, head before run by @rapiercraft-forgedock[bot] in #4948
• fix(selftest): nightly launch survives a spawn error; name a malformed sandbox_repo by @rapiercraft-forgedock[bot] in #4954
• Release: live selftest harness, nightly selftest, gate-marker exclusion in review-staging by @rapiercraft-forgedock[bot] in #4946
