One-time maintainer-authorized bootstrap merge for the release-gate verifier policy. Exact hosted CI and all supporting workflow gates passed on 66133de419.
The hardcoded `OPENCLAW_VITEST_MAX_WORKERS=4` default in gates.sh
short-circuits the host-aware scheduling introduced in c247e366.
`resolveLocalVitestScheduling` sees the explicit override and returns
maxWorkers=4, which falls below the >= 5 threshold required by
`shouldUseLargeLocalFullSuiteProfile`, so every machine—regardless of
resources—gets the DEFAULT profile (4 shard parallelism) instead of
the LARGE profile (10 shard parallelism).
Drop the hardcoded default so `test-projects.mjs` can detect actual
host resources and pick the appropriate profile automatically. When
the user explicitly sets OPENCLAW_VITEST_MAX_WORKERS, forward it as
before.
