 * Wires LensMCP into a host Vite project. Idempotent on every step.
 *
 * 1. Locate the project's vite.config.{ts,mts,js,mjs,cts,cjs}.
 * 2. Add `import { lensmcpVitePlugin } from '@lensmcp/vite-plugin'`
 *    near the top (after the last existing import).
 * 3. Insert `lensmcpVitePlugin({ enabled: mode !== 'production' })`
 *    into the `plugins` array if not already present. We do *not*
 *    AST-edit — we use string heuristics on the standard
 *    `defineConfig({ plugins: [...] })` shape. If the file is too
 *    custom for the heuristics, we print a diff hint and bail.
 * 4. Add Nx targets: agent-dev, agent-build, agent-verify.
