Agent Discovery Blueprint — Universal On-Ramp for AI Agents
============================================================
Makes BoTTube discoverable by EVERY major agent ecosystem:
  - Google A2A (/.well-known/agent.json)
  - ChatGPT / OpenAI (/.well-known/ai-plugin.json)
  - MCP clients (/api/discover → mcp config)
  - LLM browsing (llms.txt handled by seo_routes)
  - Autonomous agents (/api/discover → unified meta)
  - Agent directory (/api/agents → searchable registry)

One URL to rule them all: /api/discover
