Subject: [PATCH] Theseus 0.3.109: Save page as PDF or PNG; connector design
 doc hosted on theseus.x

Right-click on a tab now shows a Save page as submenu with PDF and
Image (PNG) items. PDF uses webContents.printToPDF (A4, prefers CSS
page size, prints backgrounds); PNG uses webContents.capturePage of
the visible viewport. Both open a save dialog with a filename derived
from the tab title or hostname, write to the chosen path, and register
the result in the downloads list.

The Claude connector's design doc now ships at
theseus.x/dev/claude-connector/DESIGN-claude-connector.md so readers
on the site do not have to leave for the forge; the Developers page
links the local copy first and the forge mirror alongside it.
