feat: add GUI checks to CI and unified release workflow

CI changes:
- Add gui-check job that builds frontend before checking Rust code
- Run on ubuntu, macos, and windows
- Uses pnpm to build the SolidJS frontend first

Release changes:
- Support tags: v*, cli-v*, gui-v*
- build-cli job: Creates CLI binaries for all platforms
- build-gui job: Creates Tauri bundles (dmg, msi, AppImage)
- Uses self-hosted runners: windows-64-cli, windows-64-cli-arm64
- Unified release job creates GitHub release with all artifacts
