* docs: add AI provider integration guide and Supported AI Providers section
Add a step-by-step guide for AI infrastructure companies to implement
ai.Model and contribute a provider to go-micro. Covers the full
lifecycle: skeleton, tool call handling, tests, registration, and PR
checklist.
Add a "Supported AI Providers" section to the project README that lists
current providers (Anthropic, OpenAI) in a table and links to the
integration guide with a call-to-action for new providers and sponsors.
Streamline the "Adding a New Provider" section in ai/README.md to point
to the new guide instead of duplicating a full code listing.
* feat(ai): add Atlas Cloud provider
Add ai/atlascloud implementing ai.Model for Atlas Cloud's
OpenAI-compatible chat completions API. Registers as "atlascloud"
with default model llama-3.3-70b and base URL
https://api.atlascloud.ai. Supports tool calling via ToolHandler.
Includes 7 unit tests covering registration, defaults, init,
generate-without-key, and stream-not-implemented.
Update the Supported AI Providers table in README.md and the
Supported Providers section in ai/README.md.
* fix: remove nonexistent Discord link from README
