Root cause of 'waiting for escalations': no queue/membership meant tickets were
never assigned. Now: createTicket find-or-creates a default queue; new joinDefault
endpoint + useGoOnline hook; agent-demo joins+goes-AVAILABLE on load (assignPending
picks up any waiting ticket). smoke-support self-seeds (no seed script needed).
Also: vitest singleFork to end cross-file DB races (45 tests deterministic).

MessageProvider/useThread/useMessages over the kernel-client socket (live append,
typing, dedupe). Reconnect test (re-opens active thread). Rewrote import-boundary
as an allowlist so SDK<->service sibling imports are forbidden both ways. 28 tests.

MessageSocket (open/send/read/typing via emitWithAck, reconnect re-opens thread,
no socket.io types leak) + RestClient (ingest/getThreadMessages/sendMessage).
tsup ESM+dts. Facade unit test with injectable fake socket (3 tests).
