/**
 * Studio Tools - Generation Middleware
 *
 * Provides Studio-compatible API endpoints backed by OpenAI/TogetherAI.
 * Matches the interface expected by Rich's frontend (frontend_v0.2).
 *
 * Endpoints:
 *   Image Generation:
 *     POST /api/generate-flux-kontext-image
 *     GET  /api/flux-kontext-status/:taskId
 *
 *   3D Generation (Meshy-compatible):
 *     POST /api/meshy/generate
 *     GET  /api/meshy/status/:taskId
 *     POST /api/meshy/download
 *
 *   3D Generation (Tripo-compatible):
 *     POST /api/tripo/generate
 *     GET  /api/tripo/task/:taskId
 *     POST /api/tripo/download/:taskId
 *
 *   Video Generation (Kling-compatible):
 *     POST /api/generate-kling-video
 *     POST /api/generate-kling-text-video
 *     POST /api/generate-kling-avatar
 *     GET  /api/kling-video-status/:taskId
