feat(di): implement attribute resolver system for dependency injection

- Introduce `ParameterAttributeResolverInterface` for handling attribute-based parameter resolution.
- Add `EnvAttributeResolver` to inject environment variables with type conversion.
- Add `LogChannelAttributeResolver` to inject channel-specific loggers.
- Create `ParameterAttributeResolverRegistry` to manage available resolvers.
- Update `ParameterResolver` to delegate attribute resolution to the registry.
- Add comprehensive unit tests for all attribute resolvers and registry functionality.
