Every range lives through insert mode, carried through each edit

Insert mode dropped the selection on the first key and restored only the
primary's appended-over span on Esc. Now each insert-mode edit is made at the
bare cursor as before, and the range is then carried through it with helix's
Range::map rules: typing slides an i range and stretches an a range, Enter
(which now also drops the blanks before the cursor, as helix does) slides or
stretches by what the cursor moved, and an arrow collapses. The replay gives
every other range the same. Esc after a pulls each range's end back by one
(helix restore_cursor), which replaces Text.append_at. The wiX-edit-drops-sel
and msel-append waivers are gone.
