2. Waitlist — Full table of signups from Vercel KV, export CSV, platform breakdown
3. Keys — Issue keys form + recently issued keys this session
4. Releases — All GitHub releases with per-asset download counts
5. Diagnostics — Env var health check (DEEPGRAM_API_KEY, ANTHROPIC_API_KEY, VOXLEN_TOKEN_SECRET), API response times
