+feat(search): edit a filter pill's value in place
+
+The filter-pill action menu now includes a searchable value picker, so you can switch a filter to a different value of the same field without removing and re-adding it. The filter's polarity (include or exclude) is preserved.

+feat(search): make active filter pills editable in place
+
+Clicking an active filter pill under the search bar now opens a small menu to copy the value or flip the filter polarity (include vs exclude), without removing and re-adding the filter. The one-click remove on each pill is unchanged.
