Move docs/ package mirror into document-navigator plugin

Relocate the ~6k-file docs tree from the repo root into
plugins/document-navigator/docs/ so the plugin is self-contained and
portable. docs/superpowers/ (specs and plans) stays at the repo root.

Moved via cp+rm rather than git mv because directory rename() fails with
EPERM on this WSL /mnt DrvFs mount; git rename-detection pairs the
identical-content files at commit time.

+import { EventBus } from "@suaveplan/events";
+import { attachEventSchemas } from "@suaveplan/events-schema";
+import z from "zod";
+
+const bus = new EventBus();
+const handle = attachEventSchemas(bus, { mode: "strict" });
+handle.registerSchema("user.created", z.object({ id: z.string() }));
+
+await bus.emitAsync("user.created", { id: "u-1" }); // passes
+await bus.emitAsync("user.created", { id: 123 });   // throws EventsSchemaError
