Replace @remixicon/react with a shared Icon component that renders
via <use href> references to a single hidden SVG sprite. This reduces
DOM node count by replacing inline SVGs with lightweight references.
- Create Icon component with sprite injection (packages/ui/src/components/icon/)
- Migrate all 164 files from @remixicon/react to Icon component
- Auto-generate sprite data from remixicon bundle (scripts/generate-icon-sprite.mjs)
- Add bun run icons:generate to package.json
- Move @remixicon/react to devDependencies
- Add icon usage instructions to theme-system skill
Removed duplicate Mini Chat launch action from the closed-sidebar header
Enabled opening Mini Chat from draft sessions via the header PiP action
Added read-only context usage info to existing Mini Chat sessions
Add dedicated Electron Mini Chat windows for focused chat sessions without the full desktop shell. Mini Chat can open existing sessions or draft sessions, supports pinning above other windows, transfers sessions or drafts back to the main window, and deduplicates existing-session windows.
Expose Mini Chat entry points from the main header, session sidebar, command palette, and `mod+alt+n`. Add a dedicated Vite entry and React runtime so the compact surface can stay isolated from full-app chrome while still sharing chat, sync, theme, locale, model, agent, and worktree behavior.
Keep Mini Chat behavior scoped to the compact surface:
- limit assistant/user message actions to the appropriate Mini Chat set
- hide workspace changed-files UI in Mini Chat
- keep draft worktree selection and streaming directory state in sync
- mark sessions viewed while they are open in Mini Chat
- support Mini Chat-specific keyboard shortcuts for input focus, model selection, thinking variant cycling, favorite model cycling, and opening new Mini Chat drafts
Harden Electron integration by gating Mini Chat controls on desktop IPC availability, restricting pin/unpin IPC to Mini Chat windows, and only closing Mini Chat after the main window handoff succeeds.
