refactor: strip to pure package library
- Fix remaining 187 pkg/ files referencing core/cli → core/go
- Move SDK library code from internal/cmd/sdk/ → pkg/sdk/ (new package)
- Create pkg/rag/helpers.go with convenience functions from internal/cmd/rag/
- Fix pkg/mcp/tools_rag.go to use pkg/rag instead of internal/cmd/rag
- Fix pkg/build/buildcmd/cmd_sdk.go and pkg/release/sdk.go to use pkg/sdk
- Remove all non-library content: main.go, internal/, cmd/, docker/,
  scripts/, tasks/, tools/, .core/, .forgejo/, .woodpecker/, Taskfile.yml
- Run go mod tidy to trim unused dependencies

core/go is now a pure Go package suite (library only).
