Preset Layout Modes for Desktop (v3.1)

The session detail view on desktop now offers three preset layout modes, accessible via a new button in the chat panel header:

Balanced
(default): An equitable split between your content tabs and the chat panel
Chat Focus
: Shrinks the left panel and expands chat, for when you want to focus on the AI conversation
Chat Only
: Shows everything in a single full-width tabbed view, including chat as its own tab

Transitions between modes are smoothly animated. Your selected mode is remembered across sessions.
