Replace fmt.Fprintf with direct hex encoding using lookup table. Add Grow() pre-allocation to eliminate builder reallocations. Benchmarks show 1.7-8x speedup depending on input: - all non-printable: 743ns -> 92ns (8x) - mixed content: 422ns -> 108ns (4x) - printable only: 242ns -> 144ns (1.7x) Allocations reduced from 2-6 to 1 in all cases.
