Pull request overview

This PR removes the (previously integrated) screenshot capture feature across the web chat shells and the desktop bridge surface area that supported it, along with the now-unused html-to-image dependency.

Changes:

• Removes screenshot UI elements (tool/overlay/button), footer controls, and the chat shell keyboard shortcut.
• Deletes screenshot-related state/helpers/tests and drops the html-to-image dependency.
• Removes the desktop captureWindow bridge/IPC handler and updates contracts accordingly; adds a regression test ensuring screenshot affordances aren’t present in the chat shell/widget shell sources.
