["JingsongLi (via GitHub)" <gi...@apache.org>]

URL: https://github.com/apache/paimon/pull/8289

   ## Summary
   
   Add Python-side support for reading Java-written bitmap global index files and cover the Java/Python interoperability path.
   
   ## Changes
   
   - Add a Python bitmap global index reader that parses bitmap index footers, dictionary blocks, block trailers, and roaring bitmaps.
   - Wire `bitmap` index dispatch into `GlobalIndexScanner`.
   - Add mixed Java/Python tests for Java bitmap index writes and Python index scans.
   - Include the bitmap index flow in `run_mixed_tests.sh`.
   
   ## Testing
   
   - `python -m py_compile pypaimon/globalindex/bitmap/bitmap_index_reader.py pypaimon/globalindex/bitmap/lazy_filtered_bitmap_reader.py pypaimon/globalindex/global_index_scanner.py pypaimon/tests/e2e/java_py_read_write_test.py`
   - `mvn -pl paimon-core -Pfast-build -Dtest=org.apache.paimon.JavaPyE2ETest#testBitmapIndexWrite -Drun.e2e.tests=true test`
   - `python -m pytest java_py_read_write_test.py::JavaPyReadWriteTest::test_read_bitmap_index_table -v`
