The runtime + compiler foundation for prebuilt binary packages, over the
existing reflection C-ABI (EV0–EV8 already gives dynamic components via
ludic_register_prop).
- ludic_register_system(fn, phase) + a registry the frame loop dispatches after
each phase's own handlers — the systems analogue of ludic_register_prop,
mirroring the EV6 foreign event-listener array. Emitted for every ECS program;
a zero-length registry means a non-hosting game is output-identical.
- --emit-module: compile a package to a position-independent module — no main,
no world table — that declares the host reflection ABI it calls and carries a
load-time constructor which registers its @System(Phase) functions and runs
module_init (where it registers its dynamic components). Built as a dylib with
-undefined dynamic_lookup, it binds ludic_* back to the host image at load.
- @System(Phase) annotation marks a module function as a runtime-registered
system; the compiler supplies its address (Ludic source cannot take one).
- The reflection ABI (world table) is now emitted for every ECS program, so any
game can host binary modules with no flag; unused defs dead-strip at -O2, so
golden renders stay byte-identical and the C-free bootstrap fixpoint holds.
Proven end-to-end: a module dylib registers a component + an Update system; a
host game that never saw its source links it and the system mutates the shared
world each frame. Full suite 87/0, test-tools 30/0, fixpoint intact.
