gpu-worker: guard portal-timing/find-number against #f form 
Root cause for repeated bend gpu-worker crashes mid-pipeline:
  ;;; bend RECV cuda-sim-ops-bin ops=monitor-r00007-c006.bin
  error: not a pair: #f

When demo_ops crashes mid-write (GPU OOM, segfault, etc) the portal
file may exist but be empty or malformed. read-from-string returns
#f. Both portal-timing + portal-find-number then call (cdr #f) =
runtime crash, taking the port-8320 listener down.

Fix: gate both walkers on (pair? form) BEFORE descending. When form
is not a pair (= #f from empty/malformed portal), return #f cleanly.
Caller's (or cpu-ms 'NA) display already handles #f.

Watchdog still exists for true OOM / kill -9, but routine empty-portal
events no longer take bend down.

Reproduces by sending a malformed S-expr to portal-find-number or
portal-timing.
