### What does this PR do? Hopefully fix https://github.com/oven-sh/bun/issues/21879 ### How did you verify your code works? Added a test with a seed larger than u32. The test vector is from this tiny test I wrote to rule out upstream zig as the culprit: ```zig const std = @import("std"); const testing = std.testing; test "xxhash64 of short string with custom seed" { const input = ""; const seed: u64 = 16269921104521594740; const hash = std.hash.XxHash64.hash(seed, input); const expected_hash: u64 = 3224619365169652240; try testing.expect(hash == expected_hash); } ```
