Changelog

All user-facing AI name references now derive from AiPersona.Name (a single

const in AiPersona.cs). XAML uses x:Static bindings, C# uses string

interpolation. Changing the AI persona name is now a one-line edit. Renamed

from Hugo to Duncan. Updated command palette entries, tray header, tooltip,

speech balloon, chat watermark, system prompt, and fallback user labels.

The IsAnyOverlayPanelOpen property included IsAiTrayOpen, which caused the

generic click-outside backdrop (ZIndex 999) to appear on top of the AI tray

drawer (ZIndex 12). Any click inside the tray hit the generic backdrop first,

immediately closing all panels. The AI tray already has its own dedicated

click-outside backdrop (AiTrayBackdrop at ZIndex 11) so it does not need the

generic overlay. Removed IsAiTrayOpen from IsAnyOverlayPanelOpen and from

CloseAllPanels to let the tray handle its own dismiss behavior.

Rename all user-facing AI references from "PrivStack AI" to "Hugo" across the

tray header, speech balloon, chat watermark, system prompt, and content

suggestion labels. Add "Open Hugo" and "Close Hugo" command items to the

command palette so users can toggle the AI tray via Cmd+K search. Bump desktop

version to 1.50.1.
