fix: prevent terminal shortcuts from intercepting keystrokes in editable elements

Replace fragile tagName checks with a robust isEditableTarget() helper that
covers input, textarea, select, and contenteditable elements. Also add
Cmd/Ctrl+Enter support and stopPropagation to the WorktreeMetaDialog comment
textarea so Enter doesn't trigger terminal handlers.
