Summary of Changes

Hello @tyrone-yu, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request primarily focuses on maintenance and minor bug fixes. It updates the Bazel version to 7.6.1 and synchronizes the MODULE.bazel.lock file. Additionally, it includes a crucial fix in the SEAL PIR algorithm's MultiplyPowerOfX function to ensure correct polynomial coefficient handling during shifts, and a small initialization improvement in a C++ synchronization utility.

Highlights

• Bazel Version Update: The USE_BAZEL_VERSION in .bazeliskrc has been updated from 7.5.0 to 7.6.1.
• Dependency Lock File Update: The MODULE.bazel.lock file was modified, specifically updating the bzlTransitiveDigest for rules_rust.
• SEAL PIR Algorithm Fix: The MultiplyPowerOfX function in seal_pir.cc was updated to correctly handle cases where the index for polynomial shifting is greater than or equal to N (polynomial modulus degree), including negating coefficients and using actual_index. The type of N was also changed from int to size_t.
• C++ Header Inclusion: Added #include <cstddef> to psi/algorithm/sealpir/seal_pir.cc.
• Synchronization Utility Initialization: The res variable in the SyncWait function within psi/utils/sync.h is now explicitly initialized.

Code Review

This pull request primarily involves dependency updates, including an upgrade of the Bazel version. It also contains a few C++ code modifications. The most significant change is in psi/algorithm/sealpir/seal_pir.cc, which refactors the logic for polynomial multiplication. My review focuses on these C++ changes. I've identified a correctness bug in seal_pir.cc that could lead to incorrect cryptographic computations under certain conditions, as well as a performance issue related to memory allocation within a loop. The change in psi/utils/sync.h is a good improvement for safer initialization. Please see the detailed comments.
