C0: retire Todoist blumeops-tasks; point task discovery at heph

Replace the Todoist-backed blumeops-tasks mise task with
`heph list --project Blumeops --json` (hephaestus, now at v1 prototype
on gilbert). Update task-discovery, rotation-reminder, and zk
references across docs; note the zk zettelkasten is migrating into
heph docs.

-`blumeops-tasks` now annotates each task with a human-readable due offset (`5d overdue` / `due in 2d` / `due today`) and a `↻ <recurrence>` marker for recurring tasks, and sorts by overdue-ness (most overdue first, no-due-date last) with priority as tiebreaker.
