"New Agent chat" opens inside the + menu: choosing "New Agent chat" from the + menu at the top of the home page now expands the Agent picker inside the menu itself, which widens naturally, instead of dismissing the menu and popping a second floating panel; a back button at the top of the picker returns to the task type list, Escape still closes the whole menu, and keyboard search and arrow-key selection behave the same as the standalone new-chat dialog (HF-14168).
Clearer "Default model" row for Runtime: the "Model" setting in a machine's Runtime details is renamed to "Default model", and the model dropdown moves from below the description text to the right side of the row; the model row title in Agent settings is unified to match (HF-14192).
Desktop notifications land on the right content: fixes clicking a desktop notification only bringing up the app window without opening what the notification was about. Clicking a notification now navigates straight to the matching task or conversation, and notifications still kept in the macOS Notification Center or the Windows Action Center open their content even after the app restarts (HF-13560).
