chore: initialize v2 — ground-up rewrite

Clean-slate rebuild on an orphan branch:
- Kernel rewritten in Go (was TypeScript)
- Web client removed
- Desktop client redone from scratch

Legacy TS implementation remains on `main` for reference.
Seeded with LICENSE (carried over), a Go-oriented .gitignore, and a minimal README.

+# Reasonix v2
+
+> DeepSeek-native coding agent — ground-up rewrite.
+
+This branch is a clean-slate rebuild:
+
+- **Kernel rewritten in Go** — the agent loop, tooling, and runtime move from TypeScript to Go.
+- **Web removed** — no web client in v2.
+- **Desktop client redone** — rebuilt from scratch.
+
+## Status
+
+🚧 Early work in progress. The architecture and layout are still taking shape.
+
+The previous TypeScript implementation (CLI + web + desktop) remains available on the
+[`main`](https://github.com/esengine/DeepSeek-Reasonix/tree/main) branch for reference.

+
+> DeepSeek 原生编码 agent —— 从零重写。
+
+本分支是全新重建：
+
+- **内核改用 Go 重写** —— agent 循环、工具与运行时从 TypeScript 迁移到 Go。
+- **去掉 web** —— v2 不再包含 web 端。
+- **重做桌面端** —— 从头重建。
+
+## 状态
+
+🚧 早期开发中，架构与目录结构尚在成形。
+
+旧版 TypeScript 实现（CLI + web + 桌面端）仍保留在
+[`main`](https://github.com/esengine/DeepSeek-Reasonix/tree/main) 分支以供参考。
