[Copilot]

Pull request overview

This PR addresses 4 security vulnerabilities in Python dependencies by upgrading filelock (3.12.2 → 3.20.1) and tornado (6.2 → 6.5.3). These dependencies are being explicitly pinned as transitive dependencies to remediate race condition and other security issues identified by Snyk.

• Adds filelock>=3.20.1 to fix race condition vulnerability (TOCTOU)
• Adds tornado>=6.5.3 to fix multiple vulnerabilities
• Addresses the tornado missing dependency warning mentioned in the PR description

The version specifications for filelock and tornado use ">=" (minimum version), while all other dependencies in this file use "==" (exact version pinning). This inconsistency could lead to unexpected behavior in different environments, as pip may install newer versions of these packages that haven't been tested with your application. Consider using exact version pinning (e.g., "filelock==3.20.1" and "tornado==6.5.3") to maintain consistency with the rest of the file and ensure reproducible builds.
