James Dansereau 7af146a1d0 D329: fix 60 fps guard anim pin (D318/D320 root cause) - tick-granularity divergence
The D318/D320 guard freeze is not a platform-invariant lock. modelTickAnim
folds numticks into one modelSetAnimFrame2WithChrStuff call, which only
advances framea/frameb when floor(frame) crosses an integer. At 1 tick/frame
(port at 60 fps) and attack speed 0.5-0.8, a pair left equal by the aim-hold
endframe clamp is re-emitted stale after the endframe is raised, so the
model pins forever. At >=2 ticks/frame (N64's normal regime) it cannot.

- model.c (#ifdef PORT, Rule-2 sign-off): when the loop did not run and the
  current endframe no longer blocks the next frame, re-derive frameb as
  modelSetAnimFrame does. GE_D329=0 disables, GE_D329LOG=1 logs triggers.
- Verified: lockstep clk=1 no longer pins (Facility ai_19, Control ai_9,
  WSL + native Windows, watchdog off); 0 triggers at clk=2; user playtest
  confirms N64-matching Ourumov timing. Bunker1 golden failure predates it
  (identical with the fix off).
- d318bprobe (TEMP, env-gated): attack-state probe + GE_D318B_CLK lockstep.
- d320repro: fix jump=<chr>,... parser (documented form never parsed).
- findings D329 + D318/D320/D321 corrections, porting-notes D13.
