Subject: [PATCH] Use multi-run median for lighthouse performance score

Single-run performance scores are noisy due to GitHub-hosted runner
CPU jitter, causing flaky CI failures unrelated to actual regressions.
numberOfRuns now defaults to 3 so lighthouse-ci reports the median
score instead of a single sample.
