Add :effects annotations to all spec files and update bootstrappers
Bootstrappers (bootstrap_py.py, js.sx) now skip :effects keyword in
define forms, enabling effect annotations throughout the spec without
changing generated output.
Annotated 180+ functions across 14 spec files:
- signals.sx: signal/deref [] pure, reset!/swap!/effect/batch [mutation]
- engine.sx: parse-* [] pure, morph-*/swap-* [mutation io]
- orchestration.sx: all [mutation io] (browser event binding)
- adapter-html.sx: render-* [render]
- adapter-dom.sx: render-* [render], reactive-* [render mutation]
- adapter-sx.sx: aser-* [render]
- adapter-async.sx: async-render-*/async-aser-* [render io]
- parser.sx: all [] pure
- render.sx: predicates [] pure, process-bindings [mutation]
- boot.sx: all [mutation io] (browser init)
- deps.sx: scan-*/transitive-* [] pure, compute-all-* [mutation]
- router.sx: all [] pure (URL matching)
