feat(chat): implement sleep pressure and insomnia system

This commit introduces a new sleep pressure and insomnia system to simulate more realistic character behavior.

Key features include:
- **Sleep Pressure**: A new metric that accumulates with each action the bot takes and decreases during scheduled sleep times.
- **Insomnia Mechanic**: When a sleep period begins, the system checks the current sleep pressure. Low pressure can lead to a higher chance of "insomnia," causing the bot to stay awake. There is also a small chance for random insomnia.
- **Insomnia State**: During insomnia, the bot enters a special state for a configurable duration. It can trigger unique proactive thoughts related to being unable to sleep, and its mood is adjusted accordingly.
- **Configuration**: All parameters, such as insomnia probability, duration, and pressure thresholds, are fully configurable.
