Plotly Studio v0.0.86: App Thumbnails and Reliability Fixes

New Features
Thumbnails for Generated Dash Apps
When the AI agent builds a Dash app for you, Studio now captures a screenshot thumbnail of it automatically. These thumbnails show up in the session view, your projects list, and the artifacts grid, making it easier to spot the app you're looking for at a glance.

Improvements
AI Calls Retry Automatically on Temporary Errors
AI requests now retry automatically when they hit a short-lived issue, such as an expired token or a brief service outage, before showing an error. This should mean fewer interruptions during agent sessions.
Faster, More Reliable Agent Sessions
The engine that runs AI agent sessions has been rebuilt for better performance and reliability across all agent-powered work in Studio.
Fixes
Fixed an issue where AI-generated app layouts with left-hand navigation could break out of the preview area and overlap Studio's own interface. Generated apps now stay contained within the preview window.
Fixed a bug where starting a new message in a session would incorrectly show an "interrupted by user" message even when nothing was actively running.
Cleaned up AI-related error messages so they no longer include unnecessary technical detail, making them easier to understand.
