Two halves of keeping the promise that storing makes.
DELETE /v1/threads/{id} is a client endpoint, not an admin one: the person who
said the thing should be able to unsay it, and making them ask an operator
would mean the operator reads it first. Deleting a thread in another project
answers exactly as deleting one that never existed does — two answers would
let a caller map which ids are real in projects they cannot read, and this one
would do it by trying to destroy them.
And something now runs the pruner. Without it "we keep conversations for 24
hours" was a comment rather than a promise: the rows would accumulate and the
number a project chose would describe nothing. Hourly, and once at startup,
because a gateway that has been down for a week should not wait another hour
before honouring a window that expired while it was off.
