Bump CI actions to Node 24 and shard the e2e job

Move actions/checkout, setup-node, cache, and upload-artifact to their current majors (Node 24 runtime). Run the browser suite as a sharded matrix aggregated by an e2e-gate job, so the required status check stays a stable name as the shard count scales. Vitest runs once (shard 1). Ready for the incoming e2e test expansion.
