Introduce user registration/login gated behind optional NEXT_PUBLIC_SUPABASE_*
env vars (leave blank to disable — app behaves exactly as before). Adds
proxy.ts for automatic cookie session refresh, requireUser() API route
guards on all 7 compute-consuming routes, AuthModal (Google/GitHub OAuth +
6-digit email OTP), UserChip header component, and login_success analytics
event. Identity is fully decoupled from Session/engine — no type changes.

Eliminate the dual code path (raw fetch vs AI SDK) for text and vision.
All providers now go through createLanguageModel() + generateText(),
removing chatOpenAiCompatible/analyzeOpenAiCompatible, the manual Usage
type, summarizeUsage, and responseFormat plumbing from 8 call sites.
Key fix: @ai-sdk/openai v3 defaults to the Responses API (/responses);
DeepSeek only supports Chat Completions, so we use .chat() explicitly.

Code-level `export const maxDuration = 60` and vercel.json `functions`
block were overriding the dashboard's 300s setting, causing ~100 504
timeouts per day on /api/scene and /api/start. Removing them lets each
Vercel plan use its own default (60s Hobby, 300s Pro) without breaking
self-deployers.

The BYO (Bring Your Own) API key configuration for LLM and image
generation will be re-implemented via Cloudflare Workers. Remove
the client-side implementation to prepare for that migration.
TTS (text-to-speech) BYO key support is intentionally preserved.
