feat(universal): route core universal modules through the cdylib mechanism (#12)

Browse Source 
apiStyle for `interface: "universal"` core modules becomes "lp" (was "std"):
they now build as header-first cdylibs — Qt-free impl + the common
module-impl C ABI export seam + uniform Qt glue, with outbound
modules().<dep> calls hitting logos-protocol's lp_* C ABI directly. An
unchanged universal module recompiles Qt-free in its impl/wrapper TUs and
still loads via the same Qt plugin (load + call ABI preserved).

UI universal backends (type: ui_qml) derive a Qt SimpleSource and cannot be
Qt-free, so they stay on the std surface. Everything else (legacy) stays qt.

Pairs with logos-module-builder modulePreConfigure.universalCodegen, which
now derives the LIDL from the impl header and runs the cdylib backend.
