/**
 * ToolFormatter - Clean, structured formatting for tool calls and results
 *
 * Uses a clean, hierarchical format:
 * ● ToolName(params)
 *   ⎿ Result summary
 *      Line-wrapped details with proper indentation
 *
 * Design principles:
 * - Bullet (●) for tool actions
 * - Tree connector (⎿) for results
 * - Automatic line wrapping at 80 chars
 * - Diff display for file edits with line numbers
 * - Clean, copy-paste friendly output
 *
