refactor: include all ws and exec data in json

[jahvon]

Refactoring and Serialization Enhancements:

• Introduced enrichedExecutable and enrichedWorkspace structs to encapsulate additional metadata (e.g., FullDescription, Namespace, Path) for better YAML/JSON serialization.

• Added custom MarshalJSON and UnmarshalJSON methods for Executable and RequestExecutableType to handle timeout serialization/deserialization as strings, ensuring compatibility with JSON formats (types/executable/executable.go).
