Function vshard_for_array_coord

nodedb-cluster/src/array_routing.rs:124–129

Compute the vShard ID for an array op at the given coordinate. The shard key is `array_name_bytes || tile_id.to_le_bytes()`, hashed via `vshard_from_key`. Falls back to `array_vshard_for_name(array_name)` when: - `coord` / `tile_extents` are empty or mismatched. - Any `tile_extents[i]` is zero. Returns a raw `u16` in `0..1023`. Callers wrap it in `VShardId::new(…)`.

(array_name: &str, coord: &[u64], tile_extents: &[u64])
