[Code Quality] Add test coverage for compiler_orchestrator_workflow.go

[github-actions]

Description

The compiler_orchestrator_workflow.go file (536 lines) has zero test coverage despite handling critical orchestration logic for the entire compilation pipeline. This represents a significant stability risk as orchestration logic and error handling paths are completely untested.

Current State

• File: pkg/workflow/compiler_orchestrator_workflow.go
• Size: 536 lines
• Test Coverage: ❌ 0 lines (no test file exists)
• Quality Score: 81/100 (loses 10 points in Testing & Maintainability)
• Risk Level: High - coordinates all compilation phases without test validation

Why This Matters (Release Mode Priority)

1. Stability Risk: Orchestration failures can break all workflow compilation
2. Error Propagation: Untested error handling paths may cause silent failures
3. Refactoring Safety: Cannot safely refactor without test coverage
4. Quality Bar: Only compiler file without dedicated tests

Suggested Changes

Create pkg/workflow/compiler_orchestrator_workflow_test.go with focus on:

1. Phase Execution Validation

   • Verify correct order: parseFrontmatterSection → setupEngineAndImports → processToolsAndMarkdown → buildInitialWorkflowData
   • Test phase dependencies and data flow between phases

2. Error Propagation Tests

   • Test error handling in each phase
   • Verify error wrapping with proper context (already has 5 fmt.Errorf(..., %w))
   • Validate early failure when phase errors occur

3. Result Struct Composition

   • Test intermediate result types between phases
   • Validate data merging from imports and top-level config
   • Test edge cases in result aggregation

4. Import Merging Logic

   • Test processAndMergeSteps() with various import scenarios
   • Validate merge deduplication and conflict resolution
   • Test custom step merging behavior

Files Affected

• New: pkg/workflow/compiler_orchestrator_workflow_test.go (~400-500 lines)
• Existing: pkg/workflow/compiler_orchestrator_workflow.go (no changes needed)

Success Criteria

• Test file created with table-driven tests
• Test-to-source ratio reaches at least 0.8:1 (~430+ test lines)
• All orchestration phases have test coverage
• Error propagation paths tested
• All existing tests pass (make test-unit)
• Quality score improves from 81/100 to 88+/100

Estimated Effort

4-6 hours - Comprehensive test creation for orchestration logic

Priority

High - Critical for release mode stability. This is the only compiler file without test coverage, representing a significant quality gap.
