chore: update CHANGELOG for v0.3.0

fix(terminal): resolve PTY shell exec error, simplify CLI, unify Config tabs, restore Studio CSS
- Fix detectShell() to return full paths via LookPath (was returning bare names causing exec error on some systems) - Add shell path validation before pty.Start to prevent crashes - Simplify CLI: remove all subcommands, keep only desktop launch with --port - Restore missing Studio shared CSS (code blocks, input area, animations) - Replace Config vertical sidebar with horizontal nav-tabs matching main layout 💘 Generated with Crush Assisted-by: GLM-5.1 via Crush <crush@charm.land>

+## [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.

-## TUI Controls
+## Desktop App — 4 Tabs

-| Key | Action |
-|-----|--------|
-| `Ctrl+T` | Open tab switcher |
-| `Tab` / `Shift+Tab` | Cycle tabs |
-| `Ctrl+C` | Quit confirmation |
-| `i` (Dashboard) | Install missing tools |
-| `u` (Dashboard) | Check for updates |
-| `s` (Dashboard) | Rescan system |
-| `a` (Workflow) | Approve plan |
-| `r` (Workflow) | Reject plan |

-| `n` (Workflow) | Next step |
-| `x` (Workflow) | Cancel workflow |
+The web UI is organized into 4 tabs with a cyberpunk dark theme. Navigate with `Ctrl+1` through `Ctrl+4`.

-### Chat Commands
+### ■ Dashboard

- `/plan <goal>` — Start a structured Plan→Execute workflow
+System overview with sub-tabs:
+- **Tools** — installed/missing tools with status badges and version info
+- **Notifications** — activity log with colored severity
+- **Workflows** — quick actions (install missing, check updates, rescan, configure MCP)
+
+### ⟨⟩ Studio
+
+AI chat interface with a sidebar containing 3 panels:
+
+| Panel | Description |
+|-------|-------------|
+| **Chat** | AI conversation, `/plan <goal>` to start workflows |
+| **Agents** | Status of Crush and Claude Code agents |
+| **Workflows** | Plan→Execute workflow controls |
+
+### $ Shell
+
+Split-view: terminal emulator on the left (sends commands to the Go backend), collapsible AI assistant panel on the right. Full command history with `↑`/`↓` navigation.
+
+### ⚙ Config
+
+Two-column profile settings:
+- **Profile** — name, pseudo, email, editor, shell, default AI, languages
+- **AI Providers** — active provider, API key status, model info
+- **Theme** — 4 swatches (Cyberpunk Red, Cyberpunk Pink, Midnight Blue, Matrix Green)
+- **Language** — FR/EN with keyboard layout selection (AZERTY, QWERTY, QWERTZ)
+- **Skills** — installed skills list
+
+### Keyboard Shortcuts

+
+The Go backend serves 15 REST endpoints under `/api/`:
+
+| Endpoint | Method | Description |
+|----------|--------|-------------|
+| `/api/info` | GET | App name, version, author |
+| `/api/system` | GET | OS, arch, platform info |
+| `/api/tools` | GET | Tool scan results |

 ## Configuration

 Config stored at `$XDG_CONFIG_HOME/muyue/config.yaml` (defaults to `~/.config/muyue/config.yaml`).

-API keys are encrypted at rest using AES-GCM with a machine-local key stored in `~/.muyue_key`.

+## Themes
+
+4 built-in themes, selectable from the Config tab:
+
+| Theme | Accent Color |
+|-------|-------------|
+| Cyberpunk Red | `#FF0033` |
+| Cyberpunk Pink | `#FF1A8C` |
+| Midnight Blue | `#0088FF` |
+| Matrix Green | `#00FF41` |
+
+Themes are applied via CSS custom properties injected at runtime. All colors (30+ variables) adapt automatically.
+
+## i18n & Keyboard Layouts
+
+- **Languages**: Français, English
+- **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)
+- Preferences saved to backend and synced across sessions
+
 ## Security

- API keys are encrypted at rest (AES-256-GCM) with a per-machine key
+- API keys encrypted at rest (AES-256-GCM) with a per-machine key
 - Config files use restrictive permissions (0600)
 - MCP config files use restrictive permissions (0600)
- Integrated terminal blocks dangerous commands (rm -rf /, mkfs, fork bombs, etc.)
+- Terminal API executes commands via shell — only accessible on localhost

 ## Cross-Platform

 Built for Linux (primary), macOS, and Windows. WSL supported.

+Single binary includes both CLI and embedded web frontend.
