/**
 * Base58 (Bitcoin / Solana alphabet) encode + decode.
 *
 * Hand-rolled to keep sigil's dependency surface small (same posture as the
 * hand-rolled keccak / RLP in src/eth). Inputs here are tiny — 32-byte
 * addresses and 64-byte signatures — so the simple BigInt long-division
 * implementation is more than fast enough; we don't need the byte-array
 * division trick.
 *
 * Leading zero bytes map to leading '1' characters (and vice versa), which is
 * what makes the all-zero 32-byte System Program key encode to 32 '1's.
