test: run the epoll sendfile e2e tests, and let CI forbid the celeris#592 rig's io_uring skips (celeris#684) - #702
Conversation
…ed since v1.5.0 (celeris#684) startFileEngine asked for Workers: 1, below resource.MinWorkers (2), so epoll.New returned "config validation: workers must be >= 2 if set, got 1" and the helper's t.Skipf turned it into a skip on every host. TestSendfileEndToEndLargeFile, TestSendfileHEADNoBody, TestSendfileRangeRequest and TestSendfileSubThresholdFallback have not run since they were added in 7beebb9, and the CI step that runs ./engine/epoll has no -v, so nothing showed it. Ask for resource.MinWorkers. Each test makes one connection and asserts on its response and on the handler's own flags, so a second worker does not change what it checks. epoll.New fails only on config validation, so a New error now fails the test instead of skipping it.

…ris#684) TestAdaptiveSettledRouteRetime592's io_uring half needs two workers, and a GitHub runner's 8 MiB of memlock funds one, so its three io_uring subtests skip in every CI step. Both of its io_uring skips (the memlock pre-flight and an engine that fails to start) now go through one helper that fails instead when CELERIS_REQUIRE_IOURING_WORKERS=1, the variable the iouring job already sets for engine/iouring's worker tests. Without the variable the rig skips exactly as before. The CI step that raises memlock and sets it comes separately.

resource.MinWorkers, and aNewerror fails the test. epoll'sNewfails only on validation, so skipping on its error was never legitimate.Each test makes one connection and asserts on the response and on the handler's own flags, so a second worker does not change what it checks.
