docs(readme): trim provider list to a few names plus docs link (#54169)

The README line enumerated 11 providers inline, which dilutes the point
and goes stale as providers come and go. Replace with Nous Portal,
OpenRouter, OpenAI, your own endpoint, and a 'many others' link to the
canonical AI Providers docs page that already lists them all.

 **The self-improving AI agent built by [Nous Research](https://nousresearch.com).** It's the only agent with a built-in learning loop — it creates skills from experience, improves them during use, nudges itself to persist knowledge, searches its own past conversations, and builds a deepening model of who you are across sessions. Run it on a $5 VPS, a GPU cluster, or serverless infrastructure that costs nearly nothing when idle. It's not tied to your laptop — talk to it from Telegram while it works on a cloud VM.
