docs(labels): the attention absolute stops denying the shipped reconciler

LABELS.md asserted 'nothing in actions/ sets, clears, reads, or validates
it' and then documented two exceptions to itself four sentences later. The
sentence is false on two of the four verbs: issueflow-reconcile.sh clears a
carried attention on the derived claimed -> post-merge transition and reads
it to gate the post-merge-assigned diagnostic. Keep the hand-set intent,
drop the absolute (#231).

 An `attention` issue without an assignee is therefore a board bug, not a
 demand; anyone may assign it or remove the flag. It never composes with
 `post-merge`, whose released claim has no assignee to answer the demand. The
