Jobs are prompts or watchers. A reminder is a prompt the agent passes on, so
it lands in the transcript. Stored reminder jobs load as prompts
("Remind me: <text>"). Also records the Coolify deploy target in CLAUDE.md.
jobs.json is { "version": 1, "jobs": [...] } in VolcanicJson camelCase,
written to jobs.json.<pid>.tmp and moved into place through one semaphore.
A corrupt file is renamed jobs.json.corrupt-<timestamp> and loading starts
empty. Each entry is deserialised on its own, so an entry with an unknown
kind or a missing required field is dropped with a warning like any other
invalid job instead of setting the whole file aside.
