refactor(service_spec_gen): split into 6 packages (types, client, config, normalize, spec, main) + .gitignore

- Split 741-line monolith into 6 independent packages
- All functions exported, no circular deps
- Build: go build -o bin/service_spec_gen ./tools/service_spec_gen/
- Script 01_generate_yamls.sh: go run → ./bin/service_spec_gen
- Add bin/ to .gitignore
