Refactor runtime executor integration and introduce eino package

- Replaced the existing runtime executor with a new eino package for better modularity.
- Updated Service struct to use the new RuntimeExecutor from eino.
- Adjusted Run and Resume methods to accommodate changes in input types and execution logic.
- Introduced new types in the eino package to align with the previous executor's functionality.
- Refactored tooling preparation logic to streamline tool definitions and improve clarity.
- Added new context builders and event consumers to enhance runtime event handling.
- Removed legacy executor code and ensured all references are updated to the new eino package.
