Update GitHub Actions to Node 24 runtime

[seasonyuu]

Summary

• Update Windows vcpkg cache restore from actions/cache@v4 to actions/cache@v5, which declares the Node 24 runtime.
• Opt GitHub Actions JavaScript actions into Node 24 with FORCE_JAVASCRIPT_ACTIONS_TO_NODE24: true so ilammy/msvc-dev-cmd@v1 no longer runs under the deprecated Node 20 runtime.
• Apply the same change to CI and Release workflows.

Verification

• Confirmed actions/cache@v5 action metadata declares using: node24.
• Confirmed current ilammy/msvc-dev-cmd@v1/v1.13.0 still declares using: node20, so the workflow-level Node 24 opt-in is required unless we replace that action.
• Local static checks passed:
  • YAML parsed for .github/workflows/ci.yml and .github/workflows/release.yml
  • git diff --check -- .github/workflows/ci.yml .github/workflows/release.yml
  • content check verified actions/cache@v5 and FORCE_JAVASCRIPT_ACTIONS_TO_NODE24: true

Notes

This keeps the existing MSVC setup behavior unchanged. A larger alternative would be replacing ilammy/msvc-dev-cmd with an inline PowerShell/vswhere setup step, but that is higher risk for the Windows ARM job.
