Summary

Standardize vcpkg.json to follow the unified_system ecosystem conventions established in common_system.

Parent Epic

Part of kcenon/common_system#251 (Epic: vcpkg.json Standardization Across Unified System Ecosystem)

Current Issues

Critical Issue

Current default dependencies include testing libraries (gtest, benchmark) and potentially unnecessary direct dependencies that should come from ecosystem packages.

Required Changes

1. Package name: messaging-system → kcenon-messaging-system
2. Add: $schema, homepage, license, port-version, supports
3. Restructure dependencies:
   • Use ecosystem packages (kcenon-common-system, kcenon-network-system, etc.)
   • Move gtest, benchmark to testing feature
   • Remove direct dependencies that come through ecosystem
4. Add: Feature flags for optional integrations
