feat(provider/openai-compatible): add textVerbosity provider option

[rahulbhadja]

Background

The @ai-sdk/openai-compatible package was missing support for the textVerbosity provider option. This caused API errors when users tried to use textVerbosity with OpenAI-compatible providers.

Summary

• Added textVerbosity option to openaiCompatibleProviderOptions schema
• Transform textVerbosity to verbosity in API request body
• Added unit tests to verify transformation and ensure no duplication in the request body
• Updated snapshot tests
• Added example file demonstrating textVerbosity usage

Manual Verification

• Created example file demonstrating textVerbosity usage: examples/ai-core/src/generate-text/openai-compatible-chat-provider-options.ts
• Built the package successfully with pnpm build
• All unit tests pass, including new textVerbosity tests
• Verified through unit tests that:
  • textVerbosity is correctly transformed to verbosity in the API request body
  • No duplicate textVerbosity field appears in requests
  • Custom options still work alongside textVerbosity
