feat(thressgame-coverage): Wave 10 (8 parity descriptors + 6 templates + perf + e2e spec)

8 parity tests (recreate ThressGame rules via descriptor JSON):
- T59 minefield: spawn mines + on-piece-entered destroys; one-shot consumption
- T60 mr_freeze: request-choice column + for-row + frozen-square spawn (lifetime moves:9)
- T61 parry: on-captured + RPS request-choice + conditional + cancel-capture
- T62 all_on_red: on-turn-start + with-probability(0.1) + BlockAllExceptKing seed (lifetime turns:5)
- T63 religious_conversion: on-move(bishop) + for-each-adjacent + set-piece-attr Color
- T64 ice_physics: on-rule-activated + for-each-piece(slider filter) + SlideMustBeMaxDistance
- T65 kamikaze: on-capture + with-probability(0.25) + for-each-adjacent + destroy-piece (king excluded)
- T66 mind_control: on-rule-activated + request-choice(forPlayer:both, LIFO stack) + for-each-piece + Color set

T67: 6 template descriptors in custom/recipes.ts (simple-mine, vampire-on-capture, frozen-column, coin-flip-restriction, religious-bishop, no-mans-land)
T68: Playwright e2e spec for 3 request-choice flows (.skip()'d pending UI integration; documents the gap)
T69: 100-marker performance budget test (p99 < 50ms via deterministic engine + perf.now timing)

Tests: 2703 -> 2740 (+37). bun run check exit 0.
