Announce retirement of public API client libraries

[andypettey]

Summary

• Adds a prominent retirement notice to the README announcing that no new versions of the client libraries will be published after November 1, 2026 (6 months from May 1, 2026).
• Explains the rationale: given the changing AI landscape, organizations are better served by generating/implementing their own clients.
• Notes that the OpenAPI specification will continue to be maintained and updated.

Test plan

• Review the README renders correctly on GitHub
• Confirm retirement date (November 1, 2026) is accurate
• Confirm messaging/tone is appropriate for public announcement
