feat(config-refs): introduce config reference parsing and resolution

- Added a new module for parsing and resolving configuration references, supporting `$SECRET_`, `$KV_`, and `$CONTEXT_` prefixes.
- Implemented functions to handle the resolution of these references within workflow contexts, enhancing the flexibility of configuration management.
- Updated existing workflows and scripts to utilize the new config reference resolution, improving data handling and context management.
- Introduced a smoke test to validate the functionality of the config reference system, ensuring robustness and reliability.

This update significantly enhances the ability to manage dynamic configurations within workflows, improving overall usability and maintainability.
