/**
 * MCP tool: get_optimization_report
 *
 * One-stop, user-facing summary of everything token-optimizer has saved:
 * total tokens saved, overall savings %, and full breakdowns by action (tool),
 * by hook phase, and by MCP server. Returns both a structured object (for
 * programmatic use / dashboards) and a pre-rendered `formatted` text report so
 * any agent can show the user a clean summary without post-processing.
