Groove Utilities Memory Log Daily

End of day memory logging for the Groove workflow system. It writes a structured markdown file to `.groove/memory/daily/` with sections for completed work, git activity, task status, learnings, and carry-forward items. The skill pulls from actual artifacts like completed tasks and git diffs rather than letting you handwave what you did. If you try to log something vague or a task lacks details, it'll ask you to clarify before writing. Designed to append to files that might already exist from morning standup, so your daily bookends stay in one place. Honest take: this is the kind of forced reflection that feels annoying until you need to remember what you actually accomplished three weeks ago.
