fix: stop creating GitHub issues on drift failure, harden collector

Remove issue creation step from fix-drift workflow — Slack
notifications to #oss-alerts remain as the sole alerting channel.

Add missing infraIndicators patterns (waitUntil timeout, AssertionError)
to drift-report-collector so it classifies WebSocket timeouts and
non-drift assertion failures as infrastructure issues instead of
crashing with "unparseable test failures."
