feat(cli): improve vix check and build reliability (smart sanitizer + global packages)

- vix check:
  - introduce smart sanitizer mode for large/umbrella projects
  - add --full flag for strict full project validation
  - fix CMake cache handling and force reconfigure when needed
  - improve global packages integration in check profiles
  - align behavior across Linux and Windows
  - enhance help with clear smart vs full sanitizer documentation

- vix build:
  - ensure global packages are always injected via CMAKE_PROJECT_TOP_LEVEL_INCLUDES
  - generate vix-global-packages.cmake consistently for all builds
  - fix missing global dependencies in build configurations
  - align build behavior with check profiles

CLI is now production-ready for real-world CMake projects.
