root 75afedaef0 feat(api): error + validate + pagination plumbing
Add lib/api/{errors,validate,pagination,index}.js: typed ApiError
subclasses, errorMiddleware, zod-backed validate(), parsePagination
with caps, and a mountApi() that owns /api routing + 404 + error tail.
server.js delegates /api to mountApi and drops the inline /api/spaces
smoke (returns in Task 2).
