Add release build configuration and MSI installer

- Configure self-contained, single-file release build
- Add version and company metadata to project
- Fix Assembly.Location for single-file compatibility (use AppContext.BaseDirectory)
- Add Resources folder copy to publish output
- Create WiX installer project with Product.wxs
- Configure auto-start via HKCU Run registry key
- Add build-release.ps1 PowerShell script for automated builds
- MSI installer installs to %LOCALAPPDATA%\DangerousThings\NFC Actions
- Creates Start Menu shortcut
- Automatically starts application on user login
