Pull request overview
This PR introduces a new conversion submodule to centralize numeric/underlying casting helpers, expands type classification concepts (e.g., *_like), and updates exports/imports so downstream code can consume the new conversion APIs.
Changes:
- Add
mcpplibs.primitives.conversion(traits + underlying casting utilities) and export it from the umbrellamcpplibs.primitivesmodule. - Refine type concepts by adding operand/“*_like” concepts to better accept primitives and/or underlying types.
- Replace legacy numeric casting helpers with the new conversion utilities and add new unit tests for conversions.

| File | Description |
|---|---|
| tests/basic/test_underlying.cpp | Removes legacy alias test; adds coverage for new meta::*_like concepts. |
| tests/basic/test_conversion.cpp | Adds tests for numeric_risk and cast variants (checked/saturating/truncating/exact) including underlying bridging. |
| src/underlying/traits.cppm | Adds underlying_operand concept (cvref-stripped underlying_type). |
| src/primitives.cppm | Exports the new mcpplibs.primitives.conversion module. |
| src/primitive/traits.cppm | Updates default policies resolution and adds meta::*_like concepts; removes legacy alias exports. |
| src/primitive/impl.cppm | Switches underlying bridging to use conversion::saturating_cast. |
| src/policy/impl.cppm | Removes legacy numeric narrowing/casting helpers; keeps to_error_payload in policy::details. |
| src/operations/operators.cppm | Switches checked overflow detection and assignment casting to conversion APIs; adds mapping from conversion risks to policy error kinds. |
| src/conversion/underlying.cppm | Implements numeric risk detection and cast operations for reps and underlying types. |
| src/conversion/traits.cppm | Defines conversion risk kinds and cast_result alias. |
| src/conversion/conversion.cppm | Aggregates and exports conversion submodules. |
