Adds the system-type kind with five modules (coding, creative-writing,
marketing, montage, business-management), an org-level enabled list
validated fail-closed, project selections limited to the org's list,
read verbs, and bus migration 3t-3u. REQ-SYS-2 toolsets are designed and
deferred: they need a role authority contract.
mosaic org delete ID --confirm ID --if-revision N, and POST /api/orgs/:id/delete,
mark the organization as deleting, stop its bus, move its files into
<dataRoot>/deleted/<ID>-<stamp>/ with a receipt, then drop it from the registry
and append deleted.log. A failure stops at its step and a rerun resumes. Bus
start refuses an organization that is being deleted. The settings page asks
twice: a panel that lists the effects, then typing the ID before Delete
permanently is enabled. Purge and remote revocation are follow-ups.
