Summary

Bumps @bitgo/wasm-utxo from ^4.16.0 to ^4.21.1 in modules/abstract-utxo/package.json.

This is one in a series of dependency bumps to pick up Nu6_3 (Ironwood) consensus branch ID support added in wasm-utxo. The new branch ID is 0x37a5165b, active from mainnet block 3,428,143.

Without this bump, the sighash builder in abstract-utxo would use the wrong branch ID for ZEC transactions at or above that height, causing invalid signatures.

Test plan

  • CI passes (unit tests for abstract-utxo)
  • No ZEC sighash regressions

T1-3705

Picks up Nu6_3 (Ironwood) consensus branch ID support (0x37a5165b,
mainnet block 3,428,143). Without this bump, the sighash builder
would use the wrong branch ID for ZEC transactions above that height.

Updated packages: abstract-utxo, utxo-bin, utxo-core, utxo-descriptors,
utxo-ord, utxo-staking.
