fix: resolve IDE warnings and test errors

Bug fixes and cleanup for test infrastructure:

- schema_test.go: Fix SchemaVersion reference with proper manifest import
- schema_test.go: Update all schema.json paths to internal/manifest location
- manifestenv.go: Remove unused helper functions (isArtifactsType, getPackagePath)
- nobaredetector.go: Fix exprToString syntax error, remove unused functions

All tests now pass without errors or warnings
