The pyworker and convert-workflows.sh both unblock when ComfyUI is
ready, but conversion takes a few seconds longer — without a wait, the
first benchmark loses the race and silently drops to the SD1.5 fallback.
Wait up to BENCHMARK_WAIT_TIMEOUT (default 30s) for the symlink before
giving up. The wait fires only when we're actually about to use the
well-known tier (env var / misc/ paths short-circuit), only once per
process, and is skipped entirely off the base image (parent directory
absent), so non-base-image deployments don't pay the timeout.
