fix: test workflow YAML indentation + add Amazonia to README

- Fix test-signal-agent.yml: last two steps were at root level instead
  of under steps — caused workflow file parse error
- Update README character count from 12 to 13 (Amazonia added)
- Add Amazonia description to bioregion characters section

 # Regen Heartbeat
 
-An observatory for the Regen ecosystem. Regen Heartbeat generates structured digests about Regen Network, RegenAI, and the Regen Commons -- pulling live data from the blockchain, the KOI knowledge commons, and the wider web, then synthesizing it into readable reports voiced through twelve distinct character personas. The digests are published as a static site via Quartz on GitHub Pages, building an accumulating record of what the ecosystem is doing, thinking, and becoming.

 This repository also serves as a working template for Claude Code. Every structural choice -- the skills, output styles, character pipeline, MCP integrations, template system -- is designed to be studied and learned from. Clone it, read it, and you will understand not just what Regen Heartbeat does, but how Claude Code works.
