chore: remove dead code (packages, functions, types, constants)

Remove 5 unused packages (daemon, preview, proxy, workflow) and dead symbols across 7 files: orchestrator workflow engine, skills Target type and Update(), LSP config generation, installer SetupPrompt(), unexported desktop options, and version License/Prerelease. Total: -1453 lines.

+## [Unreleased]
+
+### Added
+
+- **Desktop mode**: React 19 web UI served locally, auto-opens in browser. Frontend embedded in Go binary via `go:embed`.
+- **API backend**: 15 REST endpoints (`/api/info`, `/api/system`, `/api/tools`, `/api/config`, `/api/providers`, `/api/skills`, `/api/lsp`, `/api/mcp`, `/api/updates`, `/api/scan`, `/api/install`, `/api/terminal`, `/api/mcp/configure`, `/api/preferences`).
+- **i18n**: Full FR/EN translation system with keyboard layout awareness (AZERTY, QWERTY, QWERTZ). Preferences synced to backend.
+- **Themes**: 4 built-in themes (Cyberpunk Red, Cyberpunk Pink, Midnight Blue, Matrix Green) with 30+ CSS custom properties applied at runtime.
+- **Desktop flags**: `--port=PORT` to specify port, `--no-open` to skip browser auto-open.
+- **SPA routing**: Frontend handles client-side routing via catch-all fallback.
+- **CI**: Frontend build step (`npm ci && npm run build`) added to all 3 CI pipelines.
+
+### Changed
+
+- **Default mode**: `muyue` now launches the desktop web app instead of the TUI. The TUI has been removed entirely.
+- **Single binary**: `cmd/muyue-desktop` merged into `cmd/muyue`. Only one binary needed.
+- **Frontend**: Moved from `cmd/muyue-desktop/frontend/` to `web/` and embedded via `web/embed.go`.
+- **Go module**: Dependencies cleaned up — removed indirect TUI-related packages.
+- **Makefile**: `build` target now runs `frontend` (npm build) automatically. Added `dev-desktop` target for Vite dev server.
+
+### Removed
+
+- **TUI**: All `internal/tui/` code removed (model, views, handlers, animations, terminal, styles).
+- **`cmd/muyue-desktop/`**: Separate desktop binary removed; merged into main binary.

+- **Keyboard layouts**: AZERTY (fr-FR), QWERTY (en-US), QWERTZ (de-DE)
+- Keyboard layout affects displayed shortcuts in the status bar (e.g., `Ctrl+&-é-"-'` on AZERTY vs `Ctrl+1-4` on QWERTY)
