hello @mbertin-ledger This PR contains only setup of the aleo-signer package and implementation of one command - get app config. Rest of the commands and their tests will be included in the upcoming PRs.
Currently this PR contains two test files:

• packages/signer/signer-aleo/src/internal/app-binder/command/GetAppConfigCommand.test.ts
• packages/signer/signer-aleo/src/internal/app-binder/command/utils/aleoApplicationErrors.test.ts

Is there anything else that you think must be tested at this stage? @mbertin-ledger
