- GCSamplerV2 tests: add Gen0-only GC.Collect(0) calls so the V2 per-generation subtraction logic reliably reports non-zero Gen0 collections regardless of startup timing. - OTel metrics tests: wait for the OTLP export log line (fires every 5s) instead of analytic_event_data (fires at ~60s), which races with the 60-second WaitForLogLine timeout on slow CI machines. - OTel stress tests: replace the 60s analytics wait + 45s Thread.Sleep with a wait for 3 OTLP exports (~15s), cutting exercise time from ~123s to ~20s.
