Resolves vulnerabilities and CI action errors via autonomous Google Antigravity remediation task.

Google Antigravity Autonomous Resolution:

• Root Cause: Multiple Dependabot security advisories for transitive dependency filelock (alerts fix(deps): bump Python constraint to >=3.11 and Pillow to >=13.0.0 #309, fix(security): upgrade Pillow to >=13.0.0 to remediate critical vulnerabilities #310, [Security] Remediate active vulnerabilities in llmops-python-package (3 alerts) #317-#327) were open because an automated PR had accidentally downgraded filelock from 4.2.1 to 3.32.7 in poetry.lock.
• Fix Applied: Upgraded filelock to 4.2.1 in poetry.lock and verified lockfile consistency with poetry check --lock.
• Verification: Ran poetry check --lock and ruff check / ruff format --check cleanly; Gitleaks pre-commit secret scans passed.
• Pull Request: Linked and pushed to branch remediate/issue-323 (PR fix: remediate vulnerabilities and CI errors for #323 #324).
