An overridden cid mapping invalidates the auto-generated shard layout, so the override call has to provide both. Extend scx_bpf_cid_override() with a shard_start[] array that lists the first cid of each shard (starting at 0, strictly increasing, last shard implicitly extends to num_possible_cpus()). A scheduler that wants only custom shards with the auto-generated cid mapping can read the current mapping and pass it back unchanged. Overridden shards can span NUMA nodes, so scx_shard_node[] is rebuilt by majority count: each shard is assigned to the node that owns the most cpus in it. v2: Snapshot the caller's cpu_to_cid/shard_start arrays before validating.
