Subject: [PATCH] fix(ci): shard fork web tests so Chromium stops closing
 mid-run

Fork CI ran all 588 web browser test files in one headless Chromium on a
standard runner. It ran out of memory and closed partway through, failing
main and every PR on a different file each time. Upstream already shards
this suite; fork CI now does too, across four runners.
