feat: workspace topology correction — manifest in real git repo (#13)

Phase 2.6: manifest now lives in a real git repo inside the workspace.

New east init modes: -l (local), -m (remote), template (default).
ManifestSelf, ManifestConfig, Workspace rewrite with manifest_repo_path/manifest_file_path.
Breaking change: existing workspaces must be re-initialized.

166 tests passing.

+**Phase 2.6** — complete.
 
 - **Phase 1:** Multi-repo management — `east init`, `east update`, `east list`, `east status`, `east manifest --resolve`
-- **Phase 2:** Configuration & extension commands — `east config get/set/unset/list`, manifest-declared commands (`exec`/`script`/`executable`), PATH-based `east-<name>` discovery, template engine

 ## Quick Start
 
 ```bash
-# Initialize a workspace from a manifest repo
-east init https://github.com/your-org/manifest
+# Create a new workspace with a template manifest
+east init
 
-# Initialize from a specific branch
-east init https://github.com/your-org/manifest -r develop
+# Or use an existing local app as manifest repo
+east init -l ./my-app
 
-# Update all projects
+# Or clone a manifest repo from remote
+east init -m https://github.com/your-org/sdk-manifest
+
+# Update all projects declared in the manifest
 east update
 
 # Run a manifest-declared command

 ## 快速开始
 
 ```bash
-# 从 manifest 仓库初始化工作空间
-east init https://github.com/your-org/manifest
+# 创建带模板 manifest 的新 workspace
+east init
 
-# 从指定分支初始化
-east init https://github.com/your-org/manifest -r develop
+# 使用已有本地应用作为 manifest 仓库
+east init -l ./my-app
 
-# 更新所有项目
+# 从远端克隆 manifest 仓库
+east init -m https://github.com/your-org/sdk-manifest
+
+# 更新 manifest 中声明的所有项目
 east update
 
 # 运行 manifest 中声明的命令
