The project had two overlapping directories: desktop/ (Tauri Rust backend +
stale React components) and frontend/ (real React app + dead Tauri stub).
This consolidates everything under frontend/:
- Move desktop/src-tauri/ → frontend/src-tauri/ (the real 1,720-line Rust
backend with Ollama sidecar, backend lifecycle, cloud keys, overlay, etc.)
- Preserve 9 old desktop React components in frontend/src/components/Desktop/
(excluded from TS build — APIs have drifted, kept for future integration)
- Delete the old frontend/src-tauri/ stub (246 lines, never compiled)
- Delete desktop/ entirely
- Fix tauri.conf.json frontendDist path (../../frontend/dist → ../dist)
- Update CI workflow, bump script, .gitignore, and docs paths
- Rename setup/ → Setup/ for consistent PascalCase component directories
