refactor: shared YAML types via tf-tools/lib (yaml-generator + resource-generator)

TOOLS/lib/types.go — canonical ServiceSpec, ParamSpec, OperationSpec, OutputParam.
Both generators use type aliases, one source of truth for YAML contract.
docs-generator stays as-is (will be replaced by LLM-based generator).
