- can_move: `archived` is a valid source (restore). The dashboard PATCH accepts
archived -> triage/todo/ready (measured live), so the manual table gains that
row and the matrix test now measures it too. A same-column drop returns False
instead of raising or meaning "allowed".
- `hermes kanban stats` text output iterated its own hardcoded status list,
which omitted `review`; it now loops over DEFAULT_WORKFLOW.keys().
- Tests: drop three asserts that could not fail (VALID_STATUSES is
DEFAULT_STATUSES; BOARD_COLUMNS is built from keys()); add one invariant:
can_move answers for every value tasks.status can hold.
