refactor(tools): Implement ValueToolExecutor for generic tool output conversion

- Add `ValueToolExecutor` to convert tool outputs to `serde_json::Value`
- Introduce `IntoValueTool` trait for easy value type conversion
- Update agent tool addition methods to use new value conversion mechanism
- Simplify tool registration by automatically converting tool outputs
- Remove previous manual boxing and type conversion logic
