Recent lists the files opened lately, closed ones too, and a jump back to a closed file reopens it

A file closed by accident, its path forgotten, could not be found again:
the jumplist dropped closed panes. Every file opened (a look, a Save of a
scratch, a Restore, a rename) goes first in a list of 200, kept once, its
dot noted when it closes, kept across sessions in $XDG_STATE_HOME/pardes/
recent. `Recent` (SPC f r) shows it in a reused +Recent, each row
`path:line:col open|closed` a look reopens; /recent reads `open|closed
<path>`. The jumplist keeps a closed file's entries, +Jumps marks them
`(closed)`, and Back to one opens the file at its place. acme has no
such thing; its dump and Load are the nearest.
