A selection's other ranges live out of line, made at the second range and freed at one
The ranges beside the primary were an inline array in every Text, which at
1024 grew each pane by about 60 KiB. They are now allocated when a second
range appears (Text.reserveSels) and given back when the selection is one
range again (Text.dropSels); a column's or the workspace's tag allocates from
Text.gpa, any other text from its pane's. A refused tag edit restores them by
copy. The Pane size budget is back to 128 KiB, and a test holds that a single
cursor allocates nothing for them.
