Groove Utilities Memory Promises

This captures those "we'll come back to that later" moments before they vanish into the void. It stores promises as deferred tasks under a dedicated Groove Memory milestone, keeping them separate from active work but still tracked in your existing task backend. Run it bare to add a promise, use --list to see what's pending, --resolve N to check one off. The hierarchy management is automatic, so you don't create duplicate epics every time. Honest take: it's a narrow tool that does one thing cleanly. If you've ever lost track of side threads during a long session, this gives you a lightweight way to park them without context switching to a full task manager.
