refactor(layout): consolidate backend codebase into backend/ package and clean root directory

- Moved cmd/, core/, plugins/, pkg/, downstream/, and main.go into backend/ directory - Batch updated all Go source files to import github.com/Rain-kl/Wavelet/backend/... - Updated Makefile, scripts/swagger.sh, architecture guards, and platform skills - Passed all quality gates (100% tests, 0 lint issues, clean build)
