⚡ Bolt: Optimized string formatting in pkg/format

💡 What: Replaced fmt.Fprint and fmt.Fprintln with io.WriteString and w.Write using pre-allocated byte slices (tabBytes, newlineBytes) in printTabularData, printSlice, and printEvidences.

🎯 Why: fmt functions incur overhead from reflection and argument parsing, which is unnecessary for static strings like tabs and newlines. This overhead adds up in tight loops when printing large tables.

📊 Impact: Reduces execution time by ~28% for tabular output.

microscope Measurement:
Run the benchmark (was in pkg/format/benchmark_test.go):

BenchmarkPrintTabularData-4   	   20854	     52103 ns/op	   17864 B/op	     324 allocs/op

Compared to baseline:

BenchmarkPrintTabularData-4   	   18228	     67118 ns/op	   17867 B/op	     324 allocs/op
