Together CLI adds tg batches commands for batch inference

The Together CLI now includes a tg batches command group for batch inference:

• tg batches submit uploads a local JSONL file (or takes an existing file ID) and creates a job against chat.completions, audio.transcriptions, or audio.translations.
• tg batches list, retrieve, and cancel manage the job lifecycle, with ls and get as aliases.
• tg batches download streams results to stdout, or writes the output and error files to disk with --output.

See the batches CLI reference.
