codex: fix low-alch-members pacing model per governor review (bounce fix attempt 2)

- anti_ban.delay is additive to the 1.8s cast (action-grammar.md:135):
  cycle = 1.8s + 1.6-3.4s = 3.4-5.2s, midpoint 4.3s -> ~837 casts/hr
- xp_per_hour 44,640 -> 25,953; gp_per_hour range -3,177..-2,077;
  formula pinned in economy pacing block and actions a3 comment
- run_control.iteration = one full inventory+bank cycle (break.every
  counts iterations per docs/schema.md), bank-cycle claim removed
- risk note cadence pin updated; version 2 -> 3
