Enhance platform toolset configuration and CLI toolset handling

- Introduced a new configuration section in `cli-config.yaml.example` for defining platform-specific toolsets, allowing for greater customization of available tools per platform.
- Updated the CLI to check for user-defined toolsets in the configuration, falling back to the default `hermes-cli` toolset if none are specified.
- Enhanced the `GatewayRunner` class to load platform-specific toolsets from the configuration, ensuring that the correct tools are enabled based on the platform being used.
