## Summary by CodeRabbit

- **New Features**
  - Introduced automated periodic indexing of workspaces with a new job type and a scheduled cron job running every 30 seconds.
  - Added a unique sequential identifier (`sid`) and an "indexed" flag to workspaces to track indexing status.
- **Improvements**
  - Enhanced workspace indexing to handle missing workspaces and snapshots distinctly and selectively index documents.
  - Added ability to query workspaces after a given identifier with result limits.
- **Bug Fixes**
  - Improved error handling and logging during workspace indexing operations.
- **Tests**
  - Expanded test coverage for workspace indexing and auto-indexing, including scheduling and edge cases.
- **Chores**
  - Updated data models and schema to support new workspace fields and indexing features.
  - Enhanced mock data utilities to allow custom timestamps.
  - Improved type safety and flexibility in document snapshot retrieval.
