demo/bench harness polish: BT_SELF_DAMAGE_DELAY + two harness bug fixes + the OBS limp demo bat

Browse Source 
- BT_SELF_DAMAGE_DELAY=<s>: hold the harness off for n seconds (capture demos:
  healthy walking first).  Fixed its underflow bug (the countdown crossed below
  zero, which is also the "read the env" sentinel -- the delay re-armed forever).
- The one-death latch was fed by EVERY mech's update: a mission that generated
  any destroyed mech entity tripped it at frame one and the harness silently
  never fired (random per mission roll).  Now viewpoint-mech only.
- run\limpdemo.cmd: the OBS capture demo -- 30 s healthy auto-walk, then the
  leg crosses half on the final damage tick: klaxon-klaxon-"reverse disabled"
  + the limp, then unlimited limp footage (waypoint 8000,8000).
