groove-utilities-memory-promises

Use $ARGUMENTS as the promise text if provided, or a flag:

• --list: show all open promises
• --resolve <N>: mark promise N as resolved

Outcome

Deferred items from a session are captured before they are forgotten, or existing open promises are reviewed and resolved.

Acceptance Criteria

• New promise captured with date and optional context
• --list shows all open promises clearly numbered
• --resolve N marks promise N as resolved

Task backend

Read tasks.backend from .groove/index.md. Promises are tracked as tasks in the configured backend. If no task backend is configured (tasks.backend: none), tell the user to run /groove-utilities-task-install first.
