Add comprehensive unit tests for Claude Code mode: - Test claudeProviderInitializer validation and capabilities - Test header logic for beta=true query parameter - Test buildClaudeTextGenRequest for standard and Claude Code modes - Test system prompt injection when missing - Test Bash tool injection when missing - Test deduplication of existing system prompt and tools - Test constants and GetApiName Note: TransformRequestHeaders and TransformRequestBody tests are skipped as they require WASM runtime. Core logic is tested indirectly through buildClaudeTextGenRequest tests.
