Existing external-agent-registration.md is 784 lines — great reference
but hostile to first-time devs evaluating Molecule. Add a tight
5-minute quickstart aimed at "make it work today":
- 40-line Python agent with A2A JSON-RPC skeleton
- Cloudflare quick-tunnel for instant public URL (no account)
- Single curl registration
- Common gotchas table (includes the canvas dedup + tunnel rotation
issues caught in the demo this afternoon)
- Production upgrade path
- Preview of polling mode (Phase N+1 transport)
- 4-step diagnostic checklist at the bottom
The reference doc (external-agent-registration.md) now has a prominent
"in a hurry?" callout pointing at the quickstart, so the discovery
path works either way.
Target audience: a developer who wants to see their code on canvas
inside 5 minutes, not a self-hoster hardening for prod.
