Fixed 5 linter issues identified in quality assessment: - first_test.go: Check error return in BenchmarkFirst - parallel_map_test.go: Check error returns in benchmarks (2 locations) - parallel_reduce_test.go: Check error return in BenchmarkParallelReduce - foldright.go: Fix comment formatting (proper indentation) All tests pass. Linter now reports 0 issues. Quality score: 9.6/10 → 10.0/10 (perfect) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
