Create a new people list

What it does

Creates a team-visible people list (shared with the API) and returns the new list’s id.

Why you’d use it

Programmatically maintain outreach/diligence cohorts (e.g., founders, execs, domain experts) you’ll enrich, score, and sync to internal tools.

Key behaviours

• Add people at creation by passing their person IDs, or add them later via the PUT endpoint for that list id.
• The list owner will be the first team admin on your account.
• List names must be unique; if a name already exists, rename the existing list or choose a new name.
