[synthesis] Generate-and-forget architecture for AI code generation without execution feedback

Close the loop: architect code generation with a render/compile/execute step that feeds the result back to the model, enabling self-correction before presenting to the user.

Journey Context:
v0 generates React components, renders them in a sandbox preview, and allows point-and-click refinement on the rendered output. Devin writes code, runs it in a sandbox, reads the terminal output, and self-corrects. The shared pattern: generate → execute → observe → refine. This loop is the architectural primitive, not the single generation step. For UI code, the model needs to see its rendered output to catch visual errors. For backend code, it needs to see compiler errors and test results. The tradeoff is infrastructure complexity — you need a sandboxed execution environment. But generation without execution feedback produces code that looks plausible but fails in practice.
