Gemini streamEvents now convert natively; toolConfig auto-set fixed

Minor Changes

• #10924 2e28115 Thanks @christian-bromann! - feat(google-common): add native Gemini streamEvents event conversion

Patch Changes

• #10676 de0958c Thanks @jackjin1997! - Auto-set toolConfig.includeServerSideToolInvocations when a Gemini request mixes server-side built-in tools (e.g. googleSearch, codeExecution) with function declarations. The Gemini API requires this flag in that case and returns HTTP 400 without it.

• #10547 3aff161 Thanks @alex-levkivskiy! - fix(google-common): add Array.isArray guard in toolMessageToContent to prevent crash on plain object ToolMessage content
