## Description

Implement the defaults module that provides default values and resolution functions for categorical enums and node attributes. Used by construction and mutation methods to fill in unspecified fields.

## Acceptance Criteria

- [ ] `src/analysis/defaults.ts` exports default status, edge type, and attribute resolution functions
- [ ] `defaultCallStatus: CallStatus` = `"pending"`
- [ ] `defaultNodeStatus: NodeStatus` = `"idle"`
- [ ] `defaultEdgeType(edgeType?: string): EdgeType` — returns the provided type or `"typed"` (operation graph default)
- [ ] `resolveDefaultNodeAttrs(attrs: Partial<...>, defaults): NodeAttrs` — fills in missing required fields
- [ ] Unit tests: each default value is correct, resolution with partial input
