Add wrapped facade header for nlohmann/json #60
Description
Description
Add a wrapped facade header for nlohmann/json.hpp that includes nlohmann/json_fwd.hpp to make it clearer which header to include. This is to resolve clang-tidy warnings and simplify usage across the codebase.
Context
During the migration from submodule-based dependencies to task-based installation in the CLP project, it became unclear whether to include json.hpp or json_fwd.hpp, leading to inconsistent usage.

Acceptance Criteria

- Document the usage pattern for consistent implementation across projects
