Review round 2 fixes:
- Define TemplateNodeAttrs as alias for OperationNodeAttrs
- Document CallEventMapValue and CallResult types in schema.md
- Standardize CycleError naming (replace CircularDependencyError)
- Add function form to Map.over type definition
- Define Map aggregate completion/failure semantics
- Fix immutability claim for fromCallEvents
- Clarify edgeType storage alongside OperationEdgeAttrs
- Clarify WorkflowNode.status === statusMap (same Signal)
- Add component-to-tag mapping for WorkflowTag
