Forward Cargo arguments as an array and honor explicit profiles.
Build and copy each renderer target once under the repository lock,
with watch rebuilds using the same wrapper.
Select this checkout's compiler artifact and matching generated enum
table from Cargo JSON. Record actual features, profile and output paths,
and allow callers to override publication destinations.
Run the existing Cargo parser tests before the renderer's native tests
and stop on parser failures.
