spike: a plugin that serves ZAP ops without the host library

plugin/thinspike is plugin/x402's three moves — serve a typed op, ask a peer, listen — with the cloud contract removed. It is a measurement, not a migration: the delta against plugin/x402 is exactly what Mount(cloud.Router, cloud.Deps) + cloud.Listen cost. plugin/x402 602 packages 33.0 MB 3.64s plugin/thinspike 355 packages 14.3 MB 1.05s 355 is 3 packages above the floor, and the floor is zip itself (352). So the cloud contract is 247 packages of the 602 and every one of them can go; fiber is 242 of the remaining 352 and none of them can, because zip's root package imports fiber directly. thinspike imports no cloud and still links fiber/v3.
