chore: bump portfolio pin v0.13.1 -> v0.14.0 (#15)

Picks up gateway inheritance (protoLabsAI/portfolio-plugin#17): a spawned team inherits the
PM's own resolved gateway + OPENAI_API_KEY, so portfolio_spinup_team runs real turns with no
team_template / creds prep. The bundle docs (#14) already describe this.
