/**
 * OpenCode Tool Installation (Legacy)
 *
 * Version Compatibility: OpenCode versions < v1.0.186
 *
 * This module installs raggrep as an OpenCode tool for older versions of OpenCode
 * that do not support the skill system. Tools are TypeScript files placed in
 * ~/.config/opencode/tool/ that provide direct execution capabilities.
 *
 * Migration Note:
 * - Users should upgrade to OpenCode v1.0.186+ to use the newer skill-based approach
 * - This tool-based approach will be deprecated in future versions
