Ask for a ZIP of markdown of the knowledge you can read (company, project or cluster)

Queues an export; a background job builds the ZIP within about a minute (poll GET /knowledge/exports/{id}). The ZIP holds one .md per readable item (YAML front-matter: id, kind, title, path, authority, author, updatedAt, source, sourceId), manifest.json (version, company, requester, date, scope, files with sha256 and size), edges.jsonl (links between exported items) and _INDEX.md. It only contains what YOU can already read: never a colleague's personal file. Journalled in the audit log (company.storage_exported, meta.knowledge). 404 (not 403) without a company, or for a project / cluster of another company.
