fix: v2.0.2 - Node.js 安全合并 .claude.json (保留现有字段)

v2.0.1 的 PowerShell 合并会覆盖 .claude.json 现有字段 (installMethod/isLoggedIn),
导致 Claude Code 重新登录后又把 mcpServers 覆盖掉。

改用 Node.js JSON.parse/stringify 做精确字段合并:
- 读取现有 .claude.json 全部字段
- 只注入/更新 mcpServers 键
- 过滤 __comment 键
- 保留 installMethod, isLoggedIn, completedOnboarding 等
