Tantivy 0.24 adds regex phrases, cardinality aggregation

Summary

If you're building search on Rust, the regex phrase support and cardinality aggregation cut implementation friction for complex queries. Memory and merge fixes remove production footguns—especially the u32→usize bitpacker swap that previously crashed on large multivalued columns.

1. 1.RegexPhraseQuery has been added, which supports phrase queries with regex
2. 2.Cardinality aggregation allows for counting the number of distinct values in a field
3. 3.leverages HyperLogLog++, to provide a space-efficient estimation for large datasets
4. 4.Faster term fetching and reduced memory consumption for top_hits aggregation by 45%
5. 5.This enables multivalued columns larger than 4GB, which crashed during merge before
