Non-const-providers (#4396)

<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit

* **Refactor**
* Generated providers now use runtime-initialized final bindings instead
of compile-time consts.
* Provider constructors and factory initializers are non-const, and
dependency / transitive-dependency collections use non-const forms.
* Immutability/const semantics adjusted across generated code and tests;
public API names remain unchanged but initialization semantics and
related metadata are updated.
