• Added endpoint, key, and model configuration documentation plus regression coverage.

Verification

• 115 tests passed
• Ruff check and format checks passed
• Python distributions built successfully; wine check passed
• No live upstream smoke test was run because the temporary upstream endpoint and credentials are no longer available.
