feat: rebuild Process Studio into multi-phase Process Creation Wizard\n\n- Replace toy Studio.tsx with proper Wizard.tsx canvas\n- Build 6-step flow: Intake -> Analyze -> Generate -> Validate -> Draft saved -> Publish\n- Implement incremental EA2 writes via wizardApi.ts (flow, batch apply)\n- Use localStorage for draft recovery across reloads\n- Apply industrial-blueprint UI styling matching core doctrine\n- Add Vitest tests for Wizard components and API wrappers
