Add CLinks concept based on main ILinks methods

[konard]

Summary

• Implemented CLinks C++20 concept defining core requirements for ILinks interface implementations
• Used selective polymorphism approach as recommended in the issue comment referencing the AnyAny library
• Includes only main ILinks methods without extensions: Count, Each, Create, Update, Delete
• Added comprehensive tests verifying concept satisfaction for compliant and non-compliant implementations

Implementation Details

The CLinks concept requires:

Type Requirements

• LinkAddressType: Type for link addresses
• ReadHandlerType: Handler type for read operations (Each)
• WriteHandlerType: Handler type for write operations (Create, Update, Delete)

Member Requirements

• Constants: Static constants for effective interface communication
• Count(restriction): Counts links matching restriction
• Each(restriction, handler): Iterates through matching links
• Create(substitution, handler): Creates new links
• Update(restriction, substitution, handler): Updates existing links
• Delete(restriction, handler): Deletes matching links

Files Added

cpp/Platform.Data/CLinks.h

• Main concept definition with comprehensive documentation
• Self-contained with minimal dependencies (concepts, vector, type_traits)
• Added to Platform.Data.h include structure

cpp/Platform.Data.Tests/CLinksTests.cpp

• Tests using existing ILinks test infrastructure
• Verifies concept works with TestLinksForConcept implementation
• Tests different address types (uint64_t, uint32_t, uint16_t)
• Negative test for incomplete implementations

cpp/Platform.Data.Tests/CLinksSimpleTest.cpp

• Standalone concept tests without complex dependencies
• Static assertions for compile-time verification
• Simple test implementations proving concept functionality

Test Plan

• Concept compiles with C++20 standard
• Static assertions pass for compliant implementations
• Static assertions fail for incomplete implementations
• Tests work with different address types
• Integration with existing ILinks infrastructure works
• Code follows project documentation style (bilingual comments)

Based on Issue Requirements

Resolves #85 by adding a CLinks concept based on the main methods of ILinks (without extensions), following the selective polymorphism approach suggested in the issue comments.
