为此新增优化器规则：识别JOIN+WHERE+ORDER BY+LIMIT组合模式，预扫描元数据表获取匹配键，通过DuckDB区域映射修剪跳过无关存储段，构建过滤位集执行ACORN-1筛选搜索，同时保留连接计划以便重新附加元数据列。
With named trait impls it would be possible to explicitly specify that BlanketTrait should be used, similarly it would also be possible to explicitly specify that TraitBound should be used.

However, when you do have disk storage available (like an SSD), zram's block device architecture creates some significant constraints. The kernel is essentially naive to zram being any different from a typical block device on a slow disk, and so applies its normal disk-oriented defaults to it. As just one example, there is a kernel tunable called vm.page-cluster that decides how many pages we want to read ahead when we are faulting in a single swap page. It is logarithmic, so for example, if vm.page-cluster is 4, we would read in 2^4 pages to try to amortise disk work ahead of time while it's cheap and sequential. This is more important on hard drives, but there is still a meaningful performance delta between random and sequential reads even on modern NAND.
