/**
* Unit tests for interactive-adr-planning-tool.ts
* Target: Achieve comprehensive coverage for session-based ADR planning workflow
* Priority: Critical - Zero coverage currently
*
* Note: Some tests are skipped due to Jest ES modules filesystem mocking limitations.
* Tests focus on core logic validation rather than filesystem integration.
