- Populated .gitignore with Go-specific patterns - Created placeholder Go files with basic package structure: - bookstack.go: Client and Config setup - types.go: Data structures (Book, Page, Chapter, Shelf, SearchResult) - errors.go: Error handling types with sentinel errors - http.go: HTTP helper placeholder with ListOptions - books.go, pages.go, chapters.go, shelves.go, search.go: Service placeholders - Verified build succeeds with go build ./... - No external dependencies added (stdlib only) All files compile successfully and follow flat package structure.
