EloquentBrush0x 502d03d5a3 fix(kanban): detect cycles in decompose_triage_task sibling-link pre-validation
decompose_triage_task inlines SQL INSERTs for atomicity and intentionally
bypasses link_tasks() — which calls _would_cycle() per edge.  If the LLM
emits a cyclic parent graph (e.g. A.parents=[1], B.parents=[0]) the DB
write succeeds but every involved child deadlocks in 'todo' forever:
recompute_ready() requires all parents to be done, which is impossible
when A waits for B and B waits for A.

Add a Kahn topological sort over the sibling parent indices in the
pre-validation block, before any DB writes.  Mirrors the cycle-safety
guarantee that link_tasks() provides for manually linked tasks.
