The discord extension shard's silent transform/import startup (~210s measured
on a loaded macOS host) exceeded the run-vitest wrapper's 120s default
no-output timeout, so the watchdog killed healthy runs (#123025). The config
now gets the extra-long budget like the other large shards.
Three discord tests mocked openclaw/plugin-sdk/runtime-env with bare factories
missing most exports; under isolate=false they poison the shared worker module
cache and break later files that bind logVerbose/sleepWithAbort through the
shared process test harness. They now spread importOriginal and override only
their stubs.
Fixes#123025
