Fix: Use mic as fallback for STT if naudiodon fails
This commit addresses an issue where Speech-to-Text (STT) functionality would be disabled if the `naudiodon` package failed to build during installation. The `src/process/tts_process.js` file (which handles STT) has been modified to: 1. Attempt to load `naudiodon` first. 2. If `naudiodon` fails to load, attempt to load the `mic` package as an alternative. 3. The audio recording logic has been adapted to work with both `naudiodon` and `mic` APIs. Additionally, `package.json` has been updated to move `mic` from `dependencies` to `optionalDependencies`, making its behavior consistent with `naudiodon`. This change provides a fallback mechanism for audio recording, increasing the robustness of the STT feature across different platforms and environments where `naudiodon` might have build issues.
