Add Quality-of-Life Features (Speed-Up, Skip Waiting, Cooldown Indicators)

## Description
While the game is very playable, several quality-of-life features would improve the pacing and clarity of gameplay.

## Suggested Improvements
- Add a speed-up option for waves
- Allow skipping or shortening waiting time between waves
- Add cooldown timers or visual indicators for fisherman abilities

## Notes
- These features would improve player experience without changing core mechanics
- Particularly useful for repeat playthroughs or testing
