This commit refactors the entire "wakeup system" to be named "sleep system". This change provides a more intuitive and accurate name for the functionality, which manages the AI's sleep cycles, sleep pressure, and related behaviors like insomnia and flexible sleep schedules.
The renaming has been applied consistently across all relevant files, including:
- Configuration models (`WakeUpSystemConfig` -> `SleepSystemConfig`)
- Configuration files (`bot_config_template.toml`)
- Core application logic that references these configurations.
Additionally, flexible sleep and pre-sleep notification settings have been moved from the `ScheduleConfig` to the new `SleepSystemConfig` to centralize all sleep-related parameters.
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.
