Review SDK and Agent SDK functionality and documentation

Problem

The SDKs and Agent SDK should be reviewed end to end to confirm they are functional, well documented, and aligned with the current gateway API surface.

Scope

Review the TypeScript SDK, Python SDK, generated SDK surfaces, and Agent SDK documentation/examples. Identify broken flows, outdated docs, missing examples, or mismatches between documented and actual behavior.

Acceptance criteria

• Validate core SDK request flows against current gateway behavior.
• Review Agent SDK examples and documentation for accuracy.
• Confirm generated model IDs and request types are current.
• Identify any missing docs for common workflows.
• Open follow-up PRs or issues for concrete defects found during the review.
