feedback7 R22-FIELDS: an enemy whose route ends on a corner portal stays hidden 3 s inside it before it comes out of [5,10], like the explicit crossings of the same tiles (review of the #337 commit); golden: 7 fields, 4 matches — solo-NORMAL-1's Hidden Core still fails

The Grok review of fb7-fields (MEDIUM): portalPickup spliced DISAPPEAR and APPEAR with nothing between, so the enemy
vanished on [1,3] / [1,17] and stood on [5,10] in the same tick, targetable at once, while the data's explicit
crossings of the same tiles hide it: WAIT 3 s in 85 of the 95, 5 s in 9, 1 s in 1. portalPickup now splices a 3 s
WAIT (PORTAL_WAIT, the modal explicit wait) between them; [ASSUMED] the 3 s, no source times this crossing. Docs: the
SIM.md sentence and the portalPickup comment.

Tests: test/sim/portal-appear.test.js — the two route-end tests record the test enemy's hidden spans: one crossing,
entrance → [5,10], hidden 3 s (± a tick); both fail on the parent (0.000 s). 9/9.

Golden (against the 0 s version; the rounds of every match unchanged):
- matches solo-NORMAL-1 (Hidden Core boss_8 胄, act1autochess_h08_01_s): still failed — hiddenCleared false, team LP 0,
  14 rounds — with the leader left at 63897 instead of 99894 (cleared with 26 LP in 0.2.1). The same course as with
  0 s: the third vtsk, which leaked at the portal at 105 s in 0.2.1, comes out of [5,10] 3 s later, walks through the
  team's line and leaks at the door at 185.5 s (170.2 s before); 0–2 of the 8 operators stand between 100 and 320 s, the
  leader stalls near 108000 from 280 s, the overtime drain from 300 game s takes the 25 LP left by 350 s while the
  redeployed operators bring the leader to 63897 (notes trace-hidden*.mjs).
- matches solo-HARD-1 (Hidden Core failed as before): pool left 2839368 → 2982555; solo-HARD-9-boosted (cleared): team LP
  361 → 376 (383 in 0.2.1); coop2-NORMAL-14-standins (Final Assault lost as before): pool left 97588 → 108473.
- fields boss-boss_2-solo (leader left 2763024 → 2757148), boss-boss_4-solo (3759921 → 3757752), boss-boss_6-pair
  (killed 6 → 5, one hllevi_2 still walking at the 200 s cap, both players still perfect; leader 6972383 → 6932482),
  boss-boss_6-solo (3904791 → 3907393), hidden-boss_8-pair (the vtsk that comes back near the cap is still inside the
  portal at 200 s: one appear fewer, the last snapshot hash), hidden-boss_8-solo (killed 8 → 6, leaks 10 → 12),
  hidden-boss_10-solo (killed 11 → 10, leader left 7323370 → 7333760).
- unchanged by the wait: solo-FUNNY-2, coop2-ABYSS-10-boosted, the other fields, and the roster / bonds / standins / diy
  families.
