Two-stage codegen: React + Vue + Svelte from one schema

Stage 1 (framework-agnostic):
  types.ts           — OpenAPI interfaces
  contexts/<name>.ts — fetchXxxContext(params) using mizanFetch
  mutations/<name>.ts — callXxx(args) using mizanCall
  functions/<name>.ts — callXxx(args) using mizanCall
  index.ts           — re-exports

Stage 2 (per framework):
  react.tsx  — hooks + context providers + SSR hydration
  vue.ts     — composables with provide/inject + ref/computed
  svelte.ts  — writable/derived store factories

New packages:
  mizan-runtime — the kernel (~200 lines, zero framework deps)
    configure(), initSession(), registerContext(), invalidate(),
    mizanFetch(), mizanCall(), MizanError
  mizan-vue     — Vue adapter (package.json, codegen template)
  mizan-svelte  — Svelte adapter (package.json, codegen template)

CLI: mizan-generate --target react,vue,svelte
Config: target: 'react' (default) in django.config.mjs

Verified: codegen produces 33 functions across 2 contexts,
14 plain functions, 0 mutations, generating all three Stage 2
outputs from one schema fetch.
