fix(dependency-injection): honor custom scopes in toOverriding, bind(value).to(Class), and close()

[deer]

• toOverriding(Class) and bind(value).to(Class) now check findScopeEntry before falling through to the isSingleton check, mirroring the canonical bind(Class).to(Class) path. A custom-scoped concrete class no longer silently becomes a prototype in these two binding paths.
• CustomScopedClassBinding now tracks every distinct instance it produces (by identity) via its value() override.
• close() now collects instantiated CustomScopedClassBindings alongside LazySingletonClassBindings, builds a unified dependency graph over both, and invokes @PreDestroy on all tracked custom-scoped instances in reverse topological order.
