Patch Changes

• #2305 cd1daad Thanks @shrey150! - Remove the noisy AI SDK "system message in messages" warning logged on every hybrid/DOM agent.execute() call.

• #2328 d287ff4 Thanks @miguelg719! - Allow modelName "auto" in the constructor and per-primitive model overrides when running through the Stagehand API

• #2294 3938590 Thanks @seanmcguire12! - automatically close popups that violate user defined domain policy

• #2298 892701a Thanks @seanmcguire12! - Fix CUA keypress actions to press key combinations as a single chord.

• #2345 21826c7 Thanks @monadoid! - Repair malformed UTF-16 snapshot text before it reaches model prompts.

• #2306 8dcef1b Thanks @seanmcguire12! - Use the screenshot provider's declared media type when sending CUA image payloads. The setScreenshotProvider callback now returns ScreenshotProviderResult ({ base64, mediaType }) instead of a bare base64 string.

• #2273 93a23d3 Thanks @miguelg719! - Add support for the new google/gemini-3.5-flash computer-use tools model

• #2278 022d68f Thanks @shrey150! - Fix TypeError: Converting circular structure to JSON when creating an agent with MCP integrations that include a Client instance (e.g. a local/stdio server from connectToMCPServer). The agent-creation log serialized the raw integrations array, and a live MCP Client is circular. It now logs a safe descriptor (URL strings kept, client instances summarized) so agent({ integrations: [client] }) works.

• #2288 bb5ffa6 Thanks @seanmcguire12! - clean up cdp session event handlers on target detach
