fix(ui): stabilize shell rolling output transitions

- Remove anim.stop() from useRowWipe cleanup — stopping mid-animation
  leaves WAAPI fill-forward that overrides cleared inline styles. Let
  animations run to completion; cancelAnimationFrame prevents starts.
- Add generation counter to useCollapsible to guard against stale
  microtask and promise callbacks on rapid open/close toggling.
- Use .then(ok, err) instead of .catch().then() to prevent callbacks
  firing after animation cancellation.
- Remove redundant fade constant in ShellExpanded.
- Clean up unused imports in context-tool-results.tsx.

+## Sources
+
+- PR #15835: https://github.com/anomalyco/opencode/pull/15835
+
+## Do Not Translate (Locale Additions)
+
+- `OpenCode` (preserve casing in prose, docs, and UI copy)
+- Keep lowercase `opencode` in commands, package names, paths, URLs, and other exact identifiers
+- `<TAB>` stays the literal key token in code blocks; use `Tab` for the nearby explanatory label in prose
+- Commands, flags, file paths, and code literals (keep exactly as written)
+
+## Preferred Terms
+
+These are PR-backed wording preferences and may evolve.
+
+| English / Context         | Preferred                               | Notes                                                         |
+| ------------------------- | --------------------------------------- | ------------------------------------------------------------- |
+| available in beta         | `beta olarak mevcut`                    | Prefer this over `beta olarak kullanılabilir`                 |
+| privacy-first             | `Gizlilik öncelikli tasarlandı`         | Prefer this over `Önce gizlilik için tasarlandı`              |
+| connect your local models | `yerel modellerinizi bağlayabilirsiniz` | Use the fuller, more direct action phrase                     |
+| `<TAB>` key label         | `Tab`                                   | Use `Tab` in prose; keep `<TAB>` in literal UI or code blocks |
+| cross-platform            | `cross-platform (tüm platformlarda)`    | Keep the English term, add a short clarification when helpful |
+
+## Guidance
+
+- Prefer natural Turkish phrasing over literal translation
+- Merge broken sentence fragments into one clear sentence when the source is a single thought
+- Keep product naming consistent: `OpenCode` in prose, `opencode` only for exact technical identifiers
+- When an English technical term is intentionally kept, add a short Turkish clarification only if it improves readability
+
+## Avoid
+
+- Avoid `beta olarak kullanılabilir` when `beta olarak mevcut` fits
+- Avoid `Önce gizlilik için tasarlandı`; use the more natural reviewed wording instead
+- Avoid `Sekme` for the translated key label in prose when referring to `<TAB>`
+- Avoid changing `opencode` to `OpenCode` inside commands, URLs, package names, or code literals

 Prefer single word names for variables and functions. Only use multiple words if necessary.
 
+### Naming Enforcement (Read This)
+
+THIS RULE IS MANDATORY FOR AGENT WRITTEN CODE.
+
+- Use single word names by default for new locals, params, and helper functions.
+- Multi-word names are allowed only when a single word would be unclear or ambiguous.
+- Do not introduce new camelCase compounds when a short single-word alternative is clear.
+- Before finishing edits, review touched lines and shorten newly introduced identifiers where possible.
+- Good short names to prefer: `pid`, `cfg`, `err`, `opts`, `dir`, `root`, `child`, `state`, `timeout`.
+- Examples to avoid unless truly required: `inputPID`, `existingClient`, `connectTimeout`, `workerPath`.

+### Cài đặt
+
+```bash
+# YOLO
+curl -fsSL https://opencode.ai/install | bash
+
+# Các trình quản lý gói (Package managers)
+npm i -g opencode-ai@latest        # hoặc bun/pnpm/yarn
+scoop install opencode             # Windows
+choco install opencode             # Windows
+brew install anomalyco/tap/opencode # macOS và Linux (khuyên dùng, luôn cập nhật)
+brew install opencode              # macOS và Linux (công thức brew chính thức, ít cập nhật hơn)
+sudo pacman -S opencode            # Arch Linux (Bản ổn định)
+paru -S opencode-bin               # Arch Linux (Bản mới nhất từ AUR)
+mise use -g opencode               # Mọi hệ điều hành
+nix run nixpkgs#opencode           # hoặc github:anomalyco/opencode cho nhánh dev mới nhất
+```
+
+> [!TIP]
+> Hãy xóa các phiên bản cũ hơn 0.1.x trước khi cài đặt.
+
+### Ứng dụng Desktop (BETA)
+
+OpenCode cũng có sẵn dưới dạng ứng dụng desktop. Tải trực tiếp từ [trang releases](https://github.com/anomalyco/opencode/releases) hoặc [opencode.ai/download](https://opencode.ai/download).
+
+| Nền tảng              | Tải xuống                             |
+| --------------------- | ------------------------------------- |
+| macOS (Apple Silicon) | `opencode-desktop-darwin-aarch64.dmg` |
+| macOS (Intel)         | `opencode-desktop-darwin-x64.dmg`     |
+| Windows               | `opencode-desktop-windows-x64.exe`    |
+| Linux                 | `.deb`, `.rpm`, hoặc AppImage         |
+
+```bash
+# macOS (Homebrew)
+brew install --cask opencode-desktop
+# Windows (Scoop)
+scoop bucket add extras; scoop install extras/opencode-desktop
+```
+
+#### Thư mục cài đặt
+
+Tập lệnh cài đặt tuân theo thứ tự ưu tiên sau cho đường dẫn cài đặt:
+
+1. `$OPENCODE_INSTALL_DIR` - Thư mục cài đặt tùy chỉnh
+2. `$XDG_BIN_DIR` - Đường dẫn tuân thủ XDG Base Directory Specification
+3. `$HOME/bin` - Thư mục nhị phân tiêu chuẩn của người dùng (nếu tồn tại hoặc có thể tạo)
+4. `$HOME/.opencode/bin` - Mặc định dự phòng
+
+```bash
+# Ví dụ
+OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
+XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
+```
+
+### Agents (Đại diện)
+
+OpenCode bao gồm hai agent được tích hợp sẵn mà bạn có thể chuyển đổi bằng phím `Tab`.
+
+- **build** - Agent mặc định, có toàn quyền truy cập cho công việc lập trình
+- **plan** - Agent chỉ đọc dùng để phân tích và khám phá mã nguồn
+  - Mặc định từ chối việc chỉnh sửa tệp
+  - Hỏi quyền trước khi chạy các lệnh bash
+  - Lý tưởng để khám phá các codebase lạ hoặc lên kế hoạch thay đổi
+
+Ngoài ra còn có một subagent **general** dùng cho các tìm kiếm phức tạp và tác vụ nhiều bước.
+Agent này được sử dụng nội bộ và có thể gọi bằng cách dùng `@general` trong tin nhắn.
+
+Tìm hiểu thêm về [agents](https://opencode.ai/docs/agents).
+
+### Tài liệu
+
+Để biết thêm thông tin về cách cấu hình OpenCode, [**hãy truy cập tài liệu của chúng tôi**](https://opencode.ai/docs).
+
+### Đóng góp
+
+Nếu bạn muốn đóng góp cho OpenCode, vui lòng đọc [tài liệu hướng dẫn đóng góp](./CONTRIBUTING.md) trước khi gửi pull request.
+
+### Xây dựng trên nền tảng OpenCode
+
+Nếu bạn đang làm việc trên một dự án liên quan đến OpenCode và sử dụng "opencode" như một phần của tên dự án, ví dụ "opencode-dashboard" hoặc "opencode-mobile", vui lòng thêm một ghi chú vào README của bạn để làm rõ rằng dự án đó không được xây dựng bởi đội ngũ OpenCode và không liên kết với chúng tôi dưới bất kỳ hình thức nào.
+
+### Các câu hỏi thường gặp (FAQ)
+
+#### OpenCode khác biệt thế nào so với Claude Code?
+
+Về mặt tính năng, nó rất giống Claude Code. Dưới đây là những điểm khác biệt chính:
+
+- 100% mã nguồn mở
+- Không bị ràng buộc với bất kỳ nhà cung cấp nào. Mặc dù chúng tôi khuyên dùng các mô hình được cung cấp qua [OpenCode Zen](https://opencode.ai/zen), OpenCode có thể được sử dụng với Claude, OpenAI, Google, hoặc thậm chí các mô hình chạy cục bộ. Khi các mô hình phát triển, khoảng cách giữa chúng sẽ thu hẹp lại và giá cả sẽ giảm, vì vậy việc không phụ thuộc vào nhà cung cấp là rất quan trọng.
+- Hỗ trợ LSP ngay từ đầu
+- Tập trung vào TUI (Giao diện người dùng dòng lệnh). OpenCode được xây dựng bởi những người dùng neovim và đội ngũ tạo ra [terminal.shop](https://terminal.shop); chúng tôi sẽ đẩy giới hạn của những gì có thể làm được trên terminal lên mức tối đa.
+- Kiến trúc client/server. Chẳng hạn, điều này cho phép OpenCode chạy trên máy tính của bạn trong khi bạn điều khiển nó từ xa qua một ứng dụng di động, nghĩa là frontend TUI chỉ là một trong những client có thể dùng.

+ * Composer Island migration tracker
+ *
+ * Goal
+ * - Replace the split composer stack (PromptInput + question/permission/todo docks)
+ *   with a single morphing ComposerIsland + app runtime adapter.
+ *
+ * Current status
+ * - [x] Storybook prototype with morphing surfaces exists (`packages/ui/src/components/composer-island.tsx`).
+ * - [ ] App still renders the existing production stack (`session-composer-region` + `prompt-input`).
+ *
+ * Feature parity checklist
+ * - [ ] Submit pipeline parity (session/worktree/create, optimistic user message, abort, restore on error).
+ * - [x] Runtime adapter API boundary in island (`runtime.submit`, `runtime.abort`, lookup, permission/question handlers).
+ * - [x] Shell mode wiring parity (single mode source for tray + editor).
+ * - [x] Cursor scroll-into-view behavior in island editor.
+ * - [x] Attachment parity in island UI: image + PDF support and file picker wiring.
+ * - [x] Drag/drop parity in island UI: attachment drop + `file:` text drop into @mention.
+ * - [x] Keyboard parity in island UI: mod+u, ctrl+g, ctrl+n/ctrl+p, popover navigation.
+ * - [x] Auto-accept + stop/send state parity in island UI.
+ * - [x] Async @mention/slash sourcing parity in island via runtime search hooks.
+ * - [ ] Context item parity (comment chips/open behavior is in progress; app comment wiring still pending).
+ * - [ ] Question flow parity (island submit/reject hooks + sending locks done; app SDK/cache wiring pending).
+ * - [ ] Permission flow parity (island responding lock done; app tool-description wiring pending).
+ * - [x] Todo parity in island UI (in-progress pulse + auto-scroll active item).
