Generic kernel primitives so app backends (e.g. a CRM support glue) can link
their domain to interactions WITHOUT the kernel learning any app vocabulary:
- thread: accept an opaque `metadata` bag on create (merged with membership),
echo it in listThreads, and filter listThreads by `?metadata[key]=value`
(equality on the opaque bag — the kernel never interprets the keys).
- support: accept opaque `metadata` on createTicket/escalate (thread bag
inherited); add SupportService.assignTo — a policy-gated manual assignment
of a ticket to a target actor (POST /v1/support/tickets/:id/assignee).
- SDK @insignia/iios-kernel-client 0.1.2: createThread(metadata),
listThreads({metadata}) filter, createTicket(metadata), escalate(metadata),
assignTicket; ThreadSummary/Ticket expose the opaque bag.
Generic-safety gate holds: no crm/customer/lead in kernel code (opaque values
only). Tests: +2 (metadata create/filter, ticket metadata + assignTo); 31 pass.
