Joseph Doherty 464b699e18 docs(scripting): #789 §12.7 — dropping the result-dispatcher hop, measured and not kept
Measured on windev (3 alternated sessions) and macOS: a pool resume in place
of the dispatcher, and an inline-on-reader upper bound, with the harness as
committed and with its paced continuation made synchronous.

- pool: 10k/s host CPU unchanged, idle p50 and idle CPU worse (macOS idle CPU
  x3 from pool spin); only the closed loop gains. Not kept.
- inline (unsafe for every seam; the ceiling for a VirtualTag-only opt-in):
  ~8 points of a core at 10k/s raw and ~50 us idle p50 on windev with a cheap
  continuation, nothing with the harness as committed. Both budgets still
  missed by a wide margin, so the opt-in was not built.

No code change. Records the remaining attribution (harness pool hop ~15
points raw; reader wake + syscalls; worker side untouched).
