Implements ascii_fx_zone effect that allows applying arbitrary sexp effects to each character cell via cell_effect lambdas. Each cell is rendered as a small image that effects can operate on. Key changes: - New ascii_fx_zone effect with cell_effect parameter for per-cell transforms - Zone context (row, col, lum, sat, hue, etc.) available in cell_effect lambdas - Effects are now loaded explicitly from recipe declarations, not auto-loaded - Added effects_registry to plan for explicit effect dependency tracking - Updated effect definition syntax across all sexp effects - New run_staged.py for executing staged recipes - Example recipes demonstrating alternating rotation and blur/rgb_split patterns Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
