List the authenticated user's automations. An automation is a saved task for
the AI phone agent (`prompt`) that runs across one or more phones, on a
schedule (`schedule_cron` in `timezone`), when its webhook is called, or on
demand with run-automation-tool. Each run is followed with
list-automation-runs-tool and get-automation-run-tool.
`kind` is "prompt" for that, or "tiktok_warmup" for a TikTok account warm-up:
its `settings` (niche, keywords, comment language, daily window, session
counts and lengths) replace `prompt` and it has no `schedule_cron` — it plans
and runs its own sessions every day on its own timetable, and
run-automation-tool only ever starts an extra one now.
Not the same as macros (list-macros-tool), which replay recorded input exactly
with no AI. Automations are created and edited in the web app.
