Merging this PR will not alter performance

✅ 17 untouched benchmarks
⏩ 3 skipped benchmarks¹

_{Comparing filter_ref (632702a) with canary (5c24c44)}

3 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

With zero-copy FilterRef, the AMQF data lives in mmap pages that the OS can freely evict. Adding WILLNEED triggers readahead at open time so filter pages are resident for the first lookup, eliminating cold page fault overhead without pinning memory.
