Remove utxo-lib dependencies from fixed-script PSBT tests and implement fixture auto-generation. Tests now generate fixtures on-demand when missing, ensuring consistency across all signature states (unsigned, halfsigned, fullsigned). Changes: - Implement fixture generation in generateFixture.ts - Update fixtureUtil to auto-generate missing fixtures - Remove utxo-lib network references, use NetworkName type - Remove txid validation against utxo-lib - Remove OP_RETURN output construction via utxo-lib - Update all test files to use async fixture loading - Switch to format validation for txids instead of cross-library checks Issue: BTC-3047 Co-authored-by: llm-git <llm-git@ttll.de> feat(wasm-utxo): attach non_witness_utxo to PSBT inputs in AcidTest Use the new Transaction builder to construct a fake previous transaction for each input when txFormat is "psbt", populating non_witness_utxo. refactor(wasm-utxo): make txFormat a parameter in fixture generation Accept txFormat in generateAllStates() and loadPsbtFixture() instead of hardcoding "psbt-lite", enabling generation of both psbt and psbt-lite fixtures from the same infrastructure. test(wasm-utxo): run fixed-script tests across both psbt and psbt-lite formats Iterate over txFormats in parseTransactionWithWalletKeys and signAndVerifySignature, skipping psbt for zcash which doesn't support non_witness_utxo. update fixtures test(wasm-utxo): add psbt-format fixtures for all 7 coins Generate unsigned/halfsigned/fullsigned PSBT fixtures (with non_witness_utxo) for bitcoin, bitcoincash, bitcoingold, dash, dogecoin, ecash, and litecoin.

Add detailed guide for integrating new UTXO coins into wasm-utxo. Include step-by-step instructions for network enum updates, address codec configuration, PSBT handling, and fixture generation. Document match arm requirements, version byte sources, script type support flags, and sighash configuration. Provide worked example using foocoin throughout with code snippets, architecture diagram, and complete testing checklist. BTC-3047 Co-authored-by: llm-git <llm-git@ttll.de>
