Refactor EXE packaging to avoid temp files (#137)

* Refactor EXE packaging to avoid temp files

* Remove `UninstallLauncher.exe` from resources

* Refactor ExePackagingService to use IContainer and avoid intermediate disk writes

- Change BuildFromDirectory/Project to return Result<IContainer> instead of FileInfo.
- Remove direct file writing from ExePackagingService; delegate to caller via Zafiro.DivineBytes.
- Remove standalone Uninstaller.exe from output (it remains embedded in the installer).
- Update CLI ExeCommand and tests to handle the new API.

* Refactor Exe packaging to use Zafiro.DivineBytes and remove Zafiro.FileSystem dependencies
