Adds a two-step new thread modal: step one picks mode, step two
configures aspect ratio (Art mode only, six options) and resolution
(all modes: 1K/2K/4K). Settings are stored on the thread and forwarded
to the Gemini API on every send, retry, and edit. Also regenerates
icon.ico with Python to produce a clean all-BMP ICO compatible with
both Tauri's proc macro and llvm-rc cross-compilation.
Tatsumi is a Tauri desktop app for generating AI character art of Naomi
using Google Gemini's image model. Features three generation modes
(avatar, art, replace), persistent conversation threads, message
editing and deletion, retry support, cost tracking, and an about modal
with lore-accurate self-introduction from Emi Carrigan.
