Remove is_build: Cell<bool> from ProjectBuilder and introduce a new type Project. is_build==false <-> ProjectBuilder is_build==true <-> Project Also add #[must_use] to ProjectBuilder to confirm its instances are surely consumed by its build() method to produce Project. The same goes for RepoBuilder. ProjectBuilder::cargo_process() was removed as its design heavily depended on the internal mutability. Signed-off-by: NODA, Kai <nodakai@gmail.com>
