feat(bots): Consolidate bot posting into autonomous module and improve caching

- Remove scheduled posting logic and consolidate all bot posting into autonomous module
- Simplify cron endpoint to only call processAllAutonomousBots with cleaner response format
- Add background post caching for swarm follow operations via cacheSwarmUserPosts
- Update background scheduler to remove scheduled posting references and streamline logging
- Improve autonomous module documentation to clarify schedule-based posting with optional sources
- Enhance error tracking and reporting across bot task execution
- Reduce code duplication by eliminating separate scheduled/autonomous processing paths
