Subject: dumps: per-user data dir + timestamped names; Restore builtin loads a
 dump into the live session. dump.outPath resolves $PARDES_DUMP verbatim (the
 snapshot harness pins /tmp/pardes-dump.zon so dump/load/restore goldens stay
 deterministic), else $XDG_DATA_HOME|~/.local/share
 /pardes/pardes-YYYYMMDD-HHMMSS.zon (dir mkdir-ed; wall clock via libc
 clock_gettime — std.time.timestamp is gone in 0.16). After write_dump the
 shell reports the written path back (core.setLastDump) and the topbar grows
 "Restore <path>": middle-clicking Restore reloads the last dump, and "Restore
 <path>" executed anywhere takes the path as its first argument (onSelect
 prefix match). Core stays sans-IO: the builtin stashes restore_req; each
 shell consumes takeRestore() after drainEffects and swaps in initFromDump at
 the current screen size (pre-sized: dump panes never greet), tearing down the
 live ptys (tty: cancel reader + close + gen bump; gui: SIGKILL, the
 gen-guarded eof closes the old fds). Web ignores it. New restore.snap golden:
 KEEPME survives the restore, GONESOON echoed after Dump does not, the topbar
 word appears then resets. 29/29.
