fix(ts-sdk): format Together LLM provider to pass CI

Reformats the Together provider added in #5798 to match the DeepSeek
reference and satisfy the `prettier --check .` CI gate:

- Collapse manual line-wrapping in together.ts to Prettier style
- Add TOGETHER_API_BASE env override + trailing newline (parity with deepseek.ts)
- Remove stray leading blank line in factory.ts

Closes #5759
