…ect root handling

- Fix false "CMakeLists.txt not found" error caused by loose log matching
- Make handleMissingCMakeLists() strict to only trigger on real missing root cases
- Preserve actual CMake errors (e.g. missing source files) without masking them
- Improve project directory resolution fallback in BuildCommand
- Ensure correct -S path is always passed to CMake

Result:
- Accurate error reporting from CMake
- No more misleading diagnostics
- Better debugging experience for users

- add --with-sqlite and --with-mysql to vix build
- add --with-sqlite and --with-mysql to vix run
- inject DB options into generated CMake (script mode)
- extend make_script_cmakelists signature with DB flags
- propagate flags through RunDetail, RunFlow, RunScript
- add --clean support to vix run (clean build directory before configure)
- fix CheckScript call to new make_script_cmakelists signature
- keep behavior consistent between build and run commands

This enables database backends to be activated without modifying CMake manually.
