Closed all the security vulnerability issues. Most were fixed by updating dependencies, plus a few small changes:
#750

CI is passing and all test cases ran successfully. I also ran evaluations (text, TTS, STT) to make sure everything’s working fine. Whenever you all get a chance, please test on your end too—just to confirm everything’s stable after these changes
