Adds the Bitcoin Cash II coin definition (common/defs/bitcoin/bch2.json + 96x96 icon).

About: Bitcoin Cash II (BCH2) is a Bitcoin Cash protocol chain — CashAddr addresses (prefix bitcoincashii), forkId/BIP-143 signing, secp256k1, no SegWit. It reuses the Bitcoin Cash script/signing model, so no new app is needed (fork/derivative per CONTRIBUTING).

Notes:

  • SLIP-44 coin type 20145, distinct from Bitcoin Cash (145), to avoid cross-chain key reuse.
  • Shortcut BCHIIcoin_shortcut disallows digits (^t?[A-Z]{3,}$), so the ticker BCH2 is represented as BCHII; full label is "Bitcoin Cash II".
  • common/tools/cointool.py check passes (schema, SLIP-44/address/genesis collision checks all clean).
  • support.json and generated files left untouched, per the defs README guidance for external contributors.
