Addresses the clean-agent review of PR #717:
- C1: the hidden pencil was opacity-0 only, which still hit-tests; its 44px box
overhangs adjacent text, so a click in the gap between two mentions could land
on the invisible button and spuriously open the dropdown (AC-8 hole). Add
pointer-events-none while hidden, re-enabled with the opacity reveal on
hover/focus.
- C2/N1: editor.setEditable() emits "update", not a ProseMirror transaction, so
the NodeView's 'transaction' listener missed a mid-session disable flip (stale
aria-disabled/tabindex; the comment was wrong). Listen on 'update' instead —
which also skips selection-only changes, so it fires far less often.
- N2: track the node across update() so the pencil opens with the live
displayName (hardening; relink only swaps personId today).
Tests: structural guard that the hidden pencil is pointer-events-none + reveals,
and a mid-session disable-flip test (fixture gains an onReady setDisabled hook).
