[PR] Reject non-zero v1 reserved bytes [paimon-vector-index]

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

JingsongLi opened a new pull request, #36:
URL: https://github.com/apache/paimon-vector-index/pull/36

   ## Summary
   
   This PR tightens the v1 storage-format contract after #35 by requiring all reserved header bytes to be zero when reading. It also documents that index-file integrity is guaranteed by the outer Paimon file/manifest layer rather than by an embedded checksum/footer.
   
   ## Changes
   
   - Add a shared `validate_reserved_zero` helper.
   - Reject non-zero reserved bytes in IVFPQ, IVF-FLAT, IVF-HNSW-FLAT, and IVF-HNSW-SQ v1 headers.
   - Add targeted reader tests for non-zero reserved bytes across all four v1 formats.
   - Update `STORAGE_FORMAT.md` to state that reserved bytes are part of the v1 compatibility contract and must remain zero.
   - Document that checksum/length validation is handled by the outer Paimon layer.
   
   ## Testing
   
   - [x] `cargo test -p paimon-vindex-core --test storage_format_fixtures`
   - [x] `cargo test -p paimon-vindex-core --lib reserved`
   - [x] `cargo test -p paimon-vindex-core`
   - [x] `git diff --check`
