refactor(composer): represent composer via trait-based handlesrefactor/composer-handles

Replace the PartialComposer/Composer structs and the single
Rc<RefCell<PartialOrFullComposer>> enum with PartialComposer and
Composer traits (Composer: PartialComposer), InnerPartialComposer /
InnerFullComposer data structs, and the handle types FullComposerHandle
(impl Composer) and AnyComposerHandle (polymorphic enum, impl
PartialComposer), plus their weak variants.

Factory builds the full and partial graphs via separate Rc::new_cyclic
branches that share a build_composer_base helper. Call sites now use
trait methods that encapsulate borrowing instead of borrow_partial() /
composer_full*().
