Disable Windows code signing on local builds (#2438)

## Summary - Add `isGitHubActions` environment variable check to conditionally disable Windows code signing - Disable `windowsSign` in `packagerConfig` when running on GitHub Actions - Pass empty config to `MakerSquirrel` instead of signing config on GitHub Actions ## Test plan - Verify the build succeeds on GitHub Actions without Windows signing errors - Verify local builds with Windows signing still work when not on GitHub Actions #skip-bugbot 🤖 Generated with [Claude Code](https://claude.com/claude-code)  --- <a href="https://app.devin.ai/review/dyad-sh/dyad/pull/2438"> <picture> <source media="(prefers-color-scheme: dark)" srcset="https://static.devin.ai/assets/gh-open-in-devin-review-dark.svg?v=1"> <img src="https://static.devin.ai/assets/gh-open-in-devin-review-light.svg?v=1" alt="Open with Devin"> </picture> </a>   --- ## Summary by cubic Enable Windows code signing on GitHub Actions and skip it for local builds.
