Prevent CPU players from swapping 8+ value cards (8, 9, 10, J, Q) into
face-down positions, which is statistically bad since expected hidden
card value is ~4.5.
Fixes applied:
- Add value threshold (7) to unpredictability random swap path
- Restrict comeback bonus to cards with value < 8
- Reduce speculative wolfpack Jack bonus from 6x to 2x aggression
- Add safety filter to remove hidden positions for 8+ cards
- Fix endgame logic to discard 8+ instead of forcing swap into hidden
- Skip hidden positions in denial candidate list for 8+ cards
- Add swapped_high_into_unknown tracking to SimulationStats
Reduces "swapped 8+ into unknown" dumb moves from ~85 per 200 games
to ~6 per 500 games (0.054% rate, down from ~2%).

AI now considers the next player's visible cards before discarding:
- Checks if discarding would give opponent a pair opportunity
- Calculates denial value based on card value and game phase
- May keep a worse card to deny opponent when cost is acceptable
- Denial threshold varies by AI personality (aggression)
Also updates simulation to recognize denial as a valid reason for
swapping good cards, preventing false "swapped good for bad" flags.

- Fix discard pile blank/white flash on turn transitions
- Fix blank card at round end by skipping animations during round_over/game_over

- Reduce CPU initial thinking delay from 150-250ms to 80-150ms
- Pause now happens after swap completes (showing result) instead of before
