gui_toolkit 0.104.0

Added

• site.Meta.changelog_page and version_anchor: where a site tells a version (the feed's links, llms.txt), for a site whose changelog is another page or whose anchors are written otherwise (Wren's changelog/#v0-7-0).

Fixed

• Docs tables on a phone: each column keeps room for its text (26 characters, at most 70 % of the screen) and the table scrolls sideways in its frame. The columns were squeezed to one word a line.
