The compiler auto-splices runtime/native/* for any ECS game, but resolved it
relative to the build CWD, then fell back to the package module root
($LUDIC_MODULES) — forcing every external project to copy/symlink the engine
runtime into ludic_modules/. The runtime is part of the toolchain, not the
project: do_import now resolves a runtime/... import that isn't found locally
from $LUDIC_HOME (default: the compiler binary's dir — where cocoa.ll/audio.ll
already come from), before the module root. So ludic_modules/ holds only
third-party packages.
In-repo builds are byte-identical (the runtime resolves locally there, so the
$LUDIC_HOME fallback never fires; fixpoint holds). Verified by a hermetic test
that builds an ECS game from an external CWD with no runtime/ or ludic_modules/
under it, resolving the runtime from LUDIC_HOME. Full suite 113/0.
