- Add primitive_libs/ with modular primitive loading (core, math, image, color, color_ops, filters, geometry, drawing, blending, arrays, ascii) - Effects now explicitly declare dependencies via (require-primitives "...") - Convert ascii-fx-zone from hardcoded special form to loadable primitive - Add _is_symbol/_is_keyword helpers for duck typing to support both sexp_effects.parser.Symbol and artdag.sexp.parser.Symbol classes - Auto-inject _interp and _env for primitives that need them - Remove silent error swallowing in cell_effect evaluation Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
