## Summary - Add Python encoding and decoding for the unframed Java `CommitMessageSerializer` v14 body, including separate data and compact increments, current data-file metadata, index metadata, and nullable `checkFromSnapshot`. - Align Python row-id baseline validation with Java: non-null values must be equal and nonnegative, row-id file messages must carry the baseline, and reused committers clear a previous baseline. - Reconstruct local bucket paths during abort after decoding a message. Reject compact increments at the commit entry points until Python can create Java's separate COMPACT snapshot. ## Verification - Compared Python bytes with three payloads generated by Java v14: empty, index, and nested deletion-vector/global-index metadata. - `PYTHONPATH=paimon-python python -m pytest -q paimon-python/pypaimon/tests/commit_message_serializer_test.py paimon-python/pypaimon/tests/file_store_commit_test.py paimon-python/pypaimon/tests/table_commit_test.py paimon-python/pypaimon/tests/deletion_vector_path_test.py` — 132 passed, 51 skipped. - `git diff --check` passed. The serializer body carries no version header; callers carry version 14 alongside the bytes, as Java's enclosing serializer does. This PR supplies the Python wire format for a later native commit bridge. -- This is an automated message from the Apache Git Service.
