chore: standardize Python version to 3.13 across all workflows

[Copilot]

copilot-setup-steps.yml was pinned to Python 3.12 while pyproject.toml declares requires-python = ">=3.13", creating a silent mismatch where CI could pass on an unsupported runtime.

Changes

• .github/workflows/copilot-setup-steps.yml: bumped python-version from 3.12 → 3.13

# Before
- uses: actions/setup-python@v5
  with:
    python-version: '3.12'

# After
- uses: actions/setup-python@v5
  with:
    python-version: '3.13'

All three workflows that set python-version (sync.yml, performance.yml, copilot-setup-steps.yml) now consistently use 3.13, matching the project's declared minimum runtime.

<issue_title>[Code Quality] Standardize Python version across all workflows to 3.13+</issue_title>
<issue_description>### Description

Multiple workflows use Python 3.12 while pyproject.toml explicitly requires Python 3.13+. This creates inconsistencies in testing and may hide compatibility issues.

Problem

Current State:

• pyproject.toml: requires-python = ">=3.13"
• Main workflow (sync.yml): Uses Python 3.13 ✅
• Daily QA workflow: Uses Python 3.12.3 via copilot-setup-steps.yml ❌

Impact:

• Daily QA cannot test actual runtime behavior
• May miss Python 3.13-specific features or issues
• Inconsistent test results between workflows

Suggested Changes

Update .github/workflows/copilot-setup-steps.yml (or any workflow using it):

- name: Setup Python
  uses: actions/setup-python@v5
  with:
    python-version: '3.13'  # Changed from '3.12'

Files Affected

• .github/workflows/copilot-setup-steps.yml
• Any other workflows using Python 3.12 (scan all .github/workflows/*.yml)

Success Criteria

• All workflows use Python 3.13+
• grep "python-version" .github/workflows/*.yml shows only 3.13 or higher
• Daily QA workflow runs successfully on Python 3.13

Source

Extracted from Daily QA Report abhimehro/ctrld-sync#303 which identified this Python version mismatch as a critical configuration issue.

Priority

High - Affects testing accuracy and may hide compatibility bugs

Pull request overview

This PR standardizes Python version to 3.13 across all GitHub Actions workflows to match the project's minimum Python version requirement declared in pyproject.toml. Previously, copilot-setup-steps.yml was using Python 3.12, creating an inconsistency that could hide compatibility issues during CI testing.

Changes:

• Updated .github/workflows/copilot-setup-steps.yml to use Python 3.13 instead of 3.12
