feat: Implement feature flag system with helpers, service, and loader

- Added feature flag helpers and decorators for easy usage in commands.
- Created a feature flag service for managing flags, including initialization, caching, and evaluation strategies.
- Implemented a loader to initialize the feature flag service on bot startup.
- Defined types for feature flags, including configurations, contexts, evaluations, and statistics.
- Provided examples of feature flag usage in commands, demonstrating various patterns such as A/B testing, gradual rollouts, and access control.
