Update the derivation path separator in the test wallet keys function to use a period (.) instead of a slash (/) to match the TypeScript implementation in keys.ts. Issue: BTC-2893 Co-authored-by: llm-git <llm-git@ttll.de>
Add methods to create empty PSBTs and manipulate them by adding inputs and outputs. This extends the BitGoPsbt class with: - `createEmpty` static method to create new PSBTs - `addInput` method for adding transaction inputs with witness UTXO data - `addOutput` method for adding transaction outputs Issue: BTC-2893 Co-authored-by: llm-git <llm-git@ttll.de>
Add low-level PSBT parsing and comparison utilities that work at the key-value pair level. These utilities provide detailed error messages showing exactly which fields differ between two PSBTs, making debugging test failures much easier. Issue: BTC-2893 Co-authored-by: llm-git <llm-git@ttll.de>
Add complete API for PSBT construction with full wallet metadata: - Add wallet inputs with script path or key path spending - Add wallet outputs with proper derivation info - Add replay protection inputs with P2SH-P2PK scripts - Support transaction reconstruction from parsed data - Include input sequence number in parsed input data - Add version and lockTime getters to PSBT class Issue: BTC-2893 Co-authored-by: llm-git <llm-git@ttll.de>
