The PR successfully removes the claude-code provider source files, but several test files outside the diff still reference the removed provider. These will cause test failures and need to be updated.

Issues Found:

• packages/types/src/__tests__/provider-settings.test.ts (lines 10-13): Test case "should return 'anthropic' for claude-code provider" tests getApiProtocol("claude-code") which will now return "openai" instead of "anthropic" since claude-code was removed from ANTHROPIC_STYLE_PROVIDERS
• webview-ui/src/components/ui/hooks/__tests__/useSelectedModel.spec.ts (lines 415-484): Contains entire describe block "claude-code provider" that tests apiProvider: "claude-code" which is no longer a valid ProviderName
• src/core/config/__tests__/importExport.spec.ts (multiple locations): References claude-code provider in mock implementations (lines 71-78), test case for reasoning budget fields (lines 484-547), and parameterized tests (lines 1721-1791)
