docs: clarify Python SDK output and credentials

[zhongxuanwang-nv]

Overview

Clarify the Python SDK examples so users export the required NVIDIA-hosted
model credential and print the adapter response instead of the RunOutput
object identity.

This issue predates #103; that PR changes links in docs/sdk/python.mdx but
does not change the affected credential or output examples. This PR therefore
targets main directly.

Details

• Add the required NVIDIA_API_KEY export before the first Hermes example.
• Print result.output.response in both affected examples.
• Breaking changes: none.

Validation

• just docs (passed; the unauthenticated Fern redirects check was skipped)
• uv run --no-sync pre-commit run --files docs/sdk/python.mdx
• git diff --check

Where should the reviewer start?

Start with docs/sdk/python.mdx, under Start With One Run.

• I searched existing issues and open pull requests, and this does not duplicate existing work.

Summary by CodeRabbit

• Documentation
  • Updated the Python SDK “Start With One Run” example to instruct exporting NVIDIA_API_KEY before running.
  • Adjusted output display in both “Start With One Run” and “Single-Invocation Runs” to print only result.output.response (instead of the full output).

Walkthrough

The Python SDK guide adds instructions to export NVIDIA_API_KEY and updates two examples to print result.output.response instead of the full output object.
