chore: adopt modern-di 2.25 integration seams (#30)

Replace the providers_registry reach-in with container.add_providers(),
and the isinstance-on-AbstractProvider dispatch in _Dependency.__call__
with container.resolve_dependency() — same semantics, less surface
touched. Bump the modern-di floor to >=2.25.0,<3.
