Cloud <-> self-host export and import

[keysersoft]

Both directions of this are a reason people do not start.

• Someone evaluating Cloud wants to know they can leave with their configuration.
• Someone self-hosting who outgrows it wants to move without re-entering 40 connectors.

Scope

• Export a workspace: connectors, tool definitions, response mappings, MCP servers, roles, knowledge graph. Secrets excluded by design — the export names each required env var and leaves it blank.
• Import the same bundle into any instance, reporting which credentials must be supplied.
• Version-stamped, with a clear error when importing a bundle from a newer version.

This one removes a purchase objection in both directions, which is why it is above several older items.
