fix: resolve eslint and knip failures from full test suite

- Fix unnecessary type assertions in chat-completions-text and responses-text
- Fix eslint import order in ai-groq client.ts
- Fix unnecessary condition in ai-groq schema-converter combinator recursion
- Fix array-type lint error in openai-base provider-options
- Remove unused files in ai-grok (tools/index.ts, tool-converter.ts, function-tool.ts)
- Remove unused exports (createOpenAIClient, generateId, validateTextProviderOptions, InternalTextProviderOptions)
