feat(thressgame-coverage): Wave 15 (e2e for 5 parity rules + lift T68/3 parry)

Closes 5 of 5 unit-only parity rules with real Playwright validation:

- T83/all_on_red: probabilistic on-turn-start arm seeds BlockAllExceptKing (verified via UI move attempt + restoration)
- T83/ice_physics: SlideMustBeMaxDistance forces sliders to max-distance ray step (verified via legal-move highlight + drag rejection)
- T68/3 parry (lifted from .fixme): capture triggers RPS → defender wins → cancel-capture restores defender + reverts attacker
- T84/religious_conversion: bishop move converts adjacent enemy non-king pieces (verified via data-piece color flip)
- T84/kamikaze: capture triggers AOE destroying adjacent non-king; king immune (verified via DOM + RNG seed)

Helper: .sisyphus/scripts/run-pw.sh — nohup-based Playwright runner with done-marker poll. Avoids 30min agent timeout when running long e2e suites.

Tests: 2865 -> 2866 (+1 unit). E2E: 8/8 pass (was 3 active + 1 fixme; now 8 active + 0 fixme). bun run check exit 0.
