tiny-agents section feels distinct from the rest of the article, unit 1: mcp-clients

See title. The instructions don't clearly link the use of agents.json / tiny-agents to the mcp clients I think. Forgive my ignorance here, but without more clearly linking the two, It feels a bit more like an advertisement for huggingface's products. The layout of the agents.json file is a bit distinct from the examples of mcp.json files given above, and it isn't clear what each of the fields actually does.

Start in Unit 1's mcp-clients section, comparing the agents.json and mcp.json examples mentioned in the issue. Read the surrounding instructions first, then clarify how tiny-agents relates to MCP clients and explain what each agents.json field does; the section is done when that relationship and configuration are clear without requiring outside assumptions.
