Add JAX typography, xector primitives, deferred effect chains, and GPU streaming

- Add JAX text rendering with font atlas, styled text placement, and typography primitives
- Add xector (element-wise/reduction) operations library and sexp effects
- Add deferred effect chain fusion for JIT-compiled effect pipelines
- Expand drawing primitives with font management, alignment, shadow, and outline
- Add interpreter support for function-style define and require
- Add GPU persistence mode and hardware decode support to streaming
- Add new sexp effects: cell_pattern, halftone, mosaic, and derived definitions
- Add path registry for asset resolution
- Add integration, primitives, and xector tests
