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).
1. Version sync: provider/main.go = profile.env = 5.0.60
2. docs-generator: removed detectVersion() — no more dependency on provider/
3. docs-generator: removed detectRoot(), pickPath() — all paths via flags/env
4. docs-generator: require --version, --resources, --docs flags
5. Auto-rebuild: yaml-generator rebuilds if sources newer than binary
6. Three version vars → one VERSION in profile.env
7. Created TOOLS/lib/ — shared YAML contract types (not yet integrated)
