• Added inquire_team() function that prompts for team selection when multiple teams exist
• Added team_name optional field to TrainingProject model
• Added --team CLI option to truss train push command
• Updated deployment functions to accept and pass team_name parameter
• Modified upsert_training_project() API call to exclude team_name when None using exclude_none=True

🔬 Testing

$ truss train push config.py --remote baseten-staging --team team3 --job-name "archit_staging_team3"
