Registers hold a value per range, and "<reg> names one

Registers.zig replaces the one yank buffer: every register keeps a value per
range, y fills them in document order, and p, P, R and insert Ctrl-r put
value i at range i, repeating the last (helix paste_impl). "<reg> names the
register for the next command; _ swallows, # numbers the ranges, . is each
range's text, % the file's name, / the last s/S pattern, and + and * are the
system clipboard through the ClipYank and ClipPaste paths. SPC y now writes
+ alone, as helix's does. The acme chords and a paste into a terminal take
the default register joined by newlines. The msel-yank-paste waiver is gone.
