Clicking the card body outside the edit <textarea> bubbled to the card's
click handler and collapsed the card, silently discarding unsaved skill
edits (issue #4002). The textarea's own stopPropagation only shields
clicks landing on it. Bail out of the card click handler while a
.skill-md-editor is present so the card only leaves edit mode via Save
(Cancel button is handled separately by #3580). Mirrors the same guard
into the built-in capability card, which shared the bug.
