Summary

Bootstrap the GoNext monorepo with a baseline directory structure for the Go API server, Next.js public site, and admin app. Establish module boundaries that match the system topology in the architecture overview.

Design reference

• docs/00-architecture-overview.md §4 (System Topology)

Acceptance criteria

• Root go.mod initialized at module path github.com/Singleton-Solution/GoNext
• cmd/server/ contains main.go for the Go API server
• internal/ directories scaffolded: http, auth, content, media, jobs, db, config
• web/ directory contains placeholder for Next.js public site
• admin/ directory contains placeholder for admin app
• migrations/ directory exists for golang-migrate SQL files
• Top-level README.md exists with a one-line project description
• go build ./... succeeds with the empty scaffolding

Implemented via commit 1feecc4 on main (titled "docs(contributing): add policy on unsolicited AI-generated content" due to a stacked-PR mishap — see HISTORY.md for the explanation). Bootstrap monorepo code is in main and works.
