/**
 * opencode —— 统一注册 opencode 风格工具扩展。
 *
 * 聚合 files（read / edit / write 统一构建，共享 LSP service）、grep /
 * glob（ripgrep 搜索）、todo / question / bash，一次加载全部注册；各工具的
 * 公开 API（匹配引擎、纯函数等）也从这里重新导出，方便测试与其他模块
 * （如 lib/write-guard）引用。
 *
 * Usage:
 *   pi -e ./opencode/index.ts
 *
 * spawn-agent 的子代理按声明工具加载 `opencode/files.ts`，`--tools`
 * allowlist 只暴露声明的子集（与 claude-code 三件套映射同一文件一致）。
