<!-- Please specify the module before the PR name: feat: ... or fix: ... --> ### Purpose <!-- Linking this pull request to the issue --> No Linked issue. Introduce bitmap and bitset utility classes: - `RoaringBitmap32` — 32-bit roaring bitmap wrapper with serialization, set operations (and/or/xor/andnot), and iterator support (`roaring_bitmap32.h/cpp`) - `RoaringBitmap64` — 64-bit roaring bitmap wrapper with the same capabilities extended for 64-bit keys (`roaring_bitmap64.h/cpp`) - `BitSet` — compact bit vector with get/set/clear operations backed by a byte array (`bit_set.h/cpp`) <!-- What is the purpose of the change --> ### Tests - `roaring_bitmap32_test.cpp` — construction, add/remove, contains, serialization/deserialization, set operations - `roaring_bitmap64_test.cpp` — same coverage for 64-bit variant plus large-key scenarios - `bit_set_test.cpp` — bit manipulation, boundary conditions <!-- List UT and IT cases to verify this change --> ### API and Format New public headers under `include/paimon/utils/`. <!-- Does this change affect API in include dir or storage format or protocol --> ### Documentation <!-- Does this change introduce a new feature --> ### Generative AI tooling Migrate-by: Aone Copilot (Claude) <!-- If generative AI tooling has been used in the process of authoring this patch, please include the phrase: 'Generated-by: ' followed by the name of the tool and its version.
