Groove Utilities Memory Install

This sets up a structured memory system for Claude by creating a hierarchy of directories under `.groove/memory/` for different time horizons (daily, weekly, monthly), git context, outcome specs, learned knowledge, and reference docs. You'd run this once at the start of a project to establish the backend for other groove utilities that rely on persistent memory. The approach is straightforward: it just creates seven specific folders and confirms what got initialized. It's part of a larger memory management system, so on its own it won't do much, but it's the foundation other groove skills apparently depend on.
