fix: support AI SDK 7 in react-headless

[vishxrad]

Summary

• allow @openuidev/react-headless consumers to use Vercel AI SDK 6 or 7
• bump @openuidev/react-headless from 0.9.7 to 0.9.8
• update the optional-peer error and integration docs for both supported majors

Why

@openuidev/assistant-ui already accepts AI SDK 7, but its transitive @openuidev/react-headless dependency only declared ai@^6. npm therefore rejects AI SDK 7 consumers with ERESOLVE, as reported in assistant-ui#5925.

Validation

• AI SDK 6: react-headless build + 164 tests; assistant-ui typecheck + 12 tests
• AI SDK 7.0.65: react-headless build + 164 tests; assistant-ui typecheck + 12 tests
• packed both packages and installed them with ai@^7 in a clean npm consumer
• exercised UI-message streaming, message conversion, and assistant continuation against AI SDK 7
• the temporary GitHub AI SDK 7 compatibility job passed before its workflow and smoke-test script were removed

After merge, @openuidev/react-headless@0.9.8 must be published for downstream consumers to receive the widened peer range.
