d241e2a663 Add streaming video compositor with sexp interpreter
- New streaming/ module for real-time video processing:
  - compositor.py: Main streaming compositor with cycle-crossfade
  - sexp_executor.py: Executes compiled sexp recipes in real-time
  - sexp_interp.py: Full S-expression interpreter for SLICE_ON Lambda
  - recipe_adapter.py: Bridges recipes to streaming compositor
  - sources.py: Video source with ffmpeg streaming
  - audio.py: Real-time audio analysis (energy, beats)
  - output.py: Preview (mpv) and file output with audio muxing

- New templates/:
  - cycle-crossfade.sexp: Smooth zoom-based video cycling
  - process-pair.sexp: Dual-clip processing with effects

- Key features:
  - Videos cycle in input-videos order (not definition order)
  - Cumulative whole-spin rotation
  - Zero-weight sources skip processing
  - Live audio-reactive effects

- New effects: blend_multi for weighted layer compositing
- Updated primitives and interpreter for streaming compatibility

d574d5badd Add modular primitive libraries and fix Symbol class compatibility
- 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
