Update version to 0.1.20 and fix email notification aggregation

- Fix email notification aggregation to send batched notifications instead of individual emails
- Fix startup data collection to properly process initial status without triggering change notifications
- Maintain event-driven transmission while preserving aggregated notification batching
- Update version from 0.1.19 to 0.1.20 across all components
