Tools that scan agents/*.md as custom agent definitions (e.g. GitHub Copilot CLI) parse every Markdown file in agents/ and require YAML frontmatter. agents/README.md was docs, not an agent, so it triggered "malformed custom agent" warnings on every session start.
Moving the docs to docs/agents.md keeps agents/ containing only real agent definitions. Updates internal links in the moved file, in the four persona files, AGENTS.md, and adds a pointer from the root README.
Fixes#258
