Subject: [PATCH 2/2] fix(win): fix bunx command and resolve code duplication
 in shims

- Fix bunx.cmd to correctly use fast-path and add fallback to 'bun x'
- Fix bun.cmd fast-path to point to user current version instead of runtime
- Update rehash logic to use proper templates for bun/bunx shims on Windows
- Improve bvm-shim.js to handle missing bunx.exe with fallback
- Update install scripts to ensure bunx availability

+### Implementation Plan: fix_windows_bunx_20260128
+
+#### Phase 1: Core Shim & Template Optimization
+*目标：在核心代码层面修复身份识别和路由逻辑。*
+
+- [ ] Task: 更新 Windows JS Shim 模板 (`src/templates/win/bvm-shim.js`)，实现 `bunx` 到 `bun x` 的显式指令路由。 [x]
+- [ ] Task: 更新 Windows CMD 模板 (`src/templates/win/bunx.cmd` & `bun.cmd`)，为快速通道添加 `x` 路由支持。 [x]
+- [ ] Task: 优化 Unix Shim 模板 (`src/templates/unix/bvm-shim.sh`)，使用 `exec -a` 增强身份识别稳定性。 [x]
+- [ ] Task: Conductor - User Manual Verification 'Phase 1: Core Shim & Template Optimization' (Protocol in workflow.md)
+
+#### Phase 2: Installer & Self-Repair Evolution
+*目标：确保新安装及现有环境均能自动补全所需的物理文件。*
+
+- [ ] Task: 改进 `install.ps1` (Windows)，增加 `bunx.exe` 副本生成逻辑及旧版本扫描修复。 [x]
+- [ ] Task: 改进 `install.sh` (Unix)，完善运行时下载后的 `bunx` 软链接创建。 [x]
+- [ ] Task: 更新 `src/commands/setup.ts`，确保运行 `bvm setup` 时能递归修复所有已安装版本的 `bunx` 文件。 [ ]
+- [ ] Task: Conductor - User Manual Verification 'Phase 2: Installer & Self-Repair Evolution' (Protocol in workflow.md)
+
+#### Phase 3: Verification & TDD
+*目标：通过测试验证修复效果，并确保发布版本同步。*
+
+- [ ] Task: 编写或更新 `test/bunx_consistency.test.ts`，在模拟环境下验证 Windows 路由和文件补全。 [ ]
+- [ ] Task: 执行 `bun run build` 同步所有安装脚本版本，并运行全量测试。 [x]
+- [ ] Task: Conductor - User Manual Verification 'Phase 3: Verification & TDD' (Protocol in workflow.md)

+### Track Specification: fix_windows_bunx_20260128
+
+#### Overview
+修复 BVM 在 Windows 环境下 `bunx` 命令失效的问题。
+
+**当前问题证据（用户截图/日志）：**
+```powershell
+PS C:\Users\steph\OneDrive\Desktop> bunx
+Bun is a fast JavaScript runtime... (输出了帮助信息，未识别为 bunx)
+PS C:\Users\steph\OneDrive\Desktop> bunx skills add microsoft/PowerToys
+error: Script not found "skills" (身份识别错误导致路由到了 bun run 逻辑)
+```
+
+#### Functional Requirements
+1.  **显式路由逻辑**：修改 Windows 垫片（Shim）逻辑，将 `bunx <args>` 显式路由为 `bun x <args>`，确保 100% 触发 Bun 的扩展包运行逻辑。
+2.  **物理文件补全**：在安装 Bun 运行时或执行 `bvm setup` 时，确保版本 bin 目录下存在 `bunx.exe`。
+3.  **安装脚本自愈**：
+    *   更新 `install.ps1`，在安装新版本或检测到系统 Bun 时，自动补全缺失的 `bunx.exe`。
+    *   更新 `install.sh`，同步确保 Unix 环境下的 `bunx` 软链接正确。
+4.  **环境一键修复**：通过 `npm i . -g` 或 `bvm setup` 即可自动修复所有已安装版本的 `bunx` 坏道。
+5.  **版本切换支持**：`bunx` 必须严格遵循 `.bvmrc` 或全局默认版本的切换逻辑。
+
+#### Acceptance Criteria
+- [ ] **身份验证**：在 Windows 中运行 `bunx --version` 返回版本号，不再返回 Bun 的通用帮助信息。
+- [ ] **功能验证**：运行 `bunx skills add ...` 能正确识别 `skills` 为包名并执行，不再报 "Script not found"。
+- [ ] **物理验证**：重新运行 `bvm setup` 后，所有已安装版本的 `bin` 目录下均出现 `bunx` 文件。
+- [ ] **安装验证**：运行 `install.sh` 或 `install.ps1` 完成后，新安装的版本自带可运行的 `bunx`。
