PyPaimon's Python data-evolution scan previously skipped composite BTree indexes. It can now read Java-generated composite keys and use left-prefix equality, IN, NULL, and range predicates. AND queries also combine remaining scalar indexes; explicit index files can include composite indexes. Residual filtering and full/fast coverage behavior are preserved. The index format and Python index-writing APIs are unchanged.
Validation: 59 related tests and 181 subtests passed, including Java-generated BTree fixtures and table scans. Flake8 on changed files and
git diff --checkpassed.
