fix: align preflight tests with implementation (bd-lfak.2)

Fix test file to match the actual preflight.go implementation:
- Remove capitalizeFirst test (function doesn't exist)
- Rename PreflightResults -> PreflightResult
- Update truncation test to use actual truncateOutput function
- Update test data to match current Name format
