With yesterday's cron infrastructure fix in place, both daily jobs got
to actually execute today and revealed bugs that had been hiding behind
the silent failures.
1. Wiki export crashed on docs whose body starts with `---` (markdown
horizontal rule). matter.stringify(str, data) re-parses str as if
it might already contain frontmatter, so a leading `---` makes
gray-matter try to YAML-parse the body and choke on the first
`Title: subtitle` colon. Pass {content: str} instead — the parser
only runs on bare strings, so an object skips the re-parse path.
2. outline-backup.sh referenced docker container names `outline-postgres`
and `outline`, but DokPloy names containers `${project}-${service}-1`,
so the backup got `Error response from daemon: No such container`.
Derive names from $APP_NAME (set to the compose project name) with
POSTGRES_CONTAINER / OUTLINE_CONTAINER overrides for portability.
- Add cron service to docker-compose with backup (3 AM) and export (4 AM) schedules
- Remove redundant content/articles/ and content/curriculum/ (now in Outline, exported to content/wiki/)
- Fix env var mismatch: support both OUTLINE_API_KEY and OUTLINE_API_TOKEN
- Drop updatedAt from export frontmatter to reduce noisy commits
- Add backups/ to gitignore
Export script pulls all Outline documents via API and writes them as
flat markdown files to content/wiki/ with frontmatter metadata.
Cron wrapper auto-commits changes daily.
