Alphabetical sharding piled 37 of 86 packages into the [s-z] shard (every uc-* package starts with `u`), making Lint([s-z]) the ~232s CI long pole. The protected runner pool also serves only ~8-12 jobs before autoscaling kicks in, so simply adding shards trades work time for queue time and does not help wallclock. Replace alphabetical sharding with weight-balanced shards computed by scripts/ci-shards.mjs (8 shards, sized to the runner pool), and fold build, lint, and format:check into one per-shard `static` job so each shard builds its dependency closure once instead of repeating it across separate lint, typecheck, and build jobs. The standalone typecheck pass is dropped because the build task (`tsc -b`) already type-checks src while emitting, making a separate `tsc --noEmit` over the same files redundant.
