Removes docs/superpowers, which held a design note and an implementation
plan. Those were working notes rather than anything the project needs, and
they don't belong in the repo.
Everything else here is wording: em dashes swapped for ordinary
punctuation across the README and the code comments, and a few sentences
straightened out.
Task operations become pure functions over arrays.
Ids move from Date.now() to crypto.randomUUID(), with a fallback for
non-secure contexts, since people do self-host this over plain HTTP on a
LAN.
Undo gets its own module so tasks.js stays pure. It covers single deletes
and clear-completed batches, and clamps indices because the list can
change between recording an entry and undoing it.
