v0.29.0

A new look

Nushi's window is redrawn: softer corners, a floating main pane, and cards in place of lines and bars.

• The frame. The main pane floats on the window with rounded corners; the sidebar has no pane of its own, with New chat as a filled button and the agents' counts and memory as a card at its foot.
• The header is taller, with Chat / Changes as one filled control.
• The transcript and the box. Tool rows, plans, quotes and code are filled cards without side lines; the message box holds its pickers, and Queue and Stop and send are named buttons.
• Details are rounded cards in the chat pane's column.
• Changes, the Pull request tab, Settings, Jira, GitHub, Chat history, menus and dialogs follow the same surfaces.
• Notices (the daemon restarting or back, its update waiting, removed chats) float as cards under the header; nothing in the pane moves when one comes or goes, or when the sidebar hides.
• Themes. Tokyo Night is new (Night and Day), and Tokyo Night, Solarized, Nord and Catppuccin use their published colours.
• The phone's app has the new look too.
