Remove initCollectionHooks and associated migration guides

- Delete `initCollectionHooks` implementation and its usage references
- Remove `MIGRATION-v0.0.24.md` and `NOT-IMPLEMENTING.md` as they are now obsolete
- Update related workflow executor logic and TypeScript definitions, ensuring compatibility
- Simplify error handling, input parsing, and logging within workflow execution
- Clean up and refactor redundant code to improve maintainability
