Update hybrid SDK to support the Gemini Nano preview models

[gemini-code-assist]

Code Review

This pull request introduces support for selecting on-device preview model options in the Gemini Hybrid sample. It updates the UI with a new model option dropdown, adds state management in the ViewModel to check for preview model availability, and passes the selected option to the generative model configuration. Feedback highlights style guide violations, recommending that the new ModelOptionDropdown composable accept a Modifier parameter, and that the ViewModel avoid asynchronous work in its init block by utilizing a combined flow with stateIn instead. Additionally, adopting the flow approach would allow simplifying the reset function.

Important
