test(if): add golden fixture tests for if conditions

Add comprehensive golden fixture tests for if feature:
- Command-level if (true/false)
- Task-level if (true/false)
- Task calls with if conditions
- Go template functions (eq, ne, and, or)
- Direct template variable evaluation
- CLI variable overrides
- For loops with if conditions
