The selected tool updates expose timezone tests on runners without system timezone files. Add tzdata as a runtime dependency and lock its resolved version while preserving all existing locked versions. Focused timezone, data-contract and pipeline tests pass with PYTHONTZPATH=/nonexistent: 20 passed.

Supersedes #6122 after successful merged delivery.

Tasks

• Retain the selected dependency updates.
• Fix the concrete delivery blocker with focused validation.

Acceptance Criteria

• Relevant local checks pass.
• Required native CI and exact-head review gates pass.
• Verify merged delivery before closing the superseded PR.
