Initial commit: personal task planner with categories, projects, and tiered assignment

Personal-first lists/tasks/reminders/recurrence, plus an admin-editable status
pipeline, shared categories, project containers, and a three-tier permission
model for cross-user work: assign (hand off your own tasks), reallocate
(dispatcher — move anyone's tasks), admin (reserved, full manage-all).
