//! `pic triggers` subcommands.
//!
//! Three per-kind create helpers cover the most common trigger shapes
//! (KV, cron, dead_letter). For docs/files/pubsub/email/queue the
//! generic `create-from-json` accepts a raw JSON body so headless
//! operators don't get blocked waiting for per-kind wrappers.
