harness: grok-build / bash tool calls

Shell survival probe (curl-and-go #13398 style; two SEPARATE bash -c invocations):
Call1: set PROBE_ENV, define fn, umask 027, disown sleep, write /tmp/probe_bg.pid
Call2 results:
  pid: new (not same as call1)
  cwd: workspace root (not /tmp from call1)
  env: unset
  fn: gone
  umask: 0022 (not 027)
  bg: alive (via pid file + disown)
Reproduce:
  bash -c 'cd /tmp; export PROBE_ENV=set; umask 027; nohup sleep 240 >/dev/null 2>&1 & disown; echo $! >/tmp/probe_bg.pid'
  bash -c 'echo env=${PROBE_ENV:-unset}; umask; kill -0 $(cat /tmp/probe_bg.pid) && echo bg=alive'
