Add a concise Client Configuration section that explains how to configureAI coding tools to use AI Bridge. This includes:- Base URL configuration for OpenAI and Anthropic endpoints- Authentication using Coder session tokens/API keys- General compatibility notes without specific client detailsThis is a focused extraction from the broader aibridge-provider-docs branch,containing only the essential setup information without client-specific guides.

…bility notes- Added a reference to using `data.coder_workspace_owner.me.session_token` in templates for generating Coder API keys.- Reformatted the 'Compatibility Notes' section for better clarity, and revised some details about client-specific requirements.

- Clarify that OPENAI_BASE_URL and ANTHROPIC_BASE_URL are commonly environment  variables but configuration methods vary by client- Reframe authentication section from operator perspective, referring to 'users'  and 'their' keys rather than 'your' keys- Make it clear operators don't distribute provider keys to users

Update the session token configuration line to be explicitly for templateadmins who are setting up authentication for their users, rather thansounding like it's for end users themselves.

…I coding assistants. Include specific examples such as removing the `/v1` suffix for URL formats and note clients like Cursor that proxy requests through their servers. Highlight instances where custom base URLs are not supported, as in Copilot CLI and Sourcegraph Amp.
