feat: add stereo synthesis option via SBV2_FORCE_STEREO env var

873bbb77b6 feat: add stereo synthesis option via SBV2_FORCE_STEREO env var 
Previously, synthesis output was fixed to mono (channels=1).
Now, setting the environment variable SBV2_FORCE_STEREO=1 forces stereo (2-channel) output.

This allows generating stereo audio without changing the code, useful for users needing dual-channel output.
