"""Tests: vault.* JSON-RPC handlers (tui_gateway/methods_vault.py).

The Desktop's Settings → Credential Vault panel. Contracts:
- vault.list returns metadata only — secret values must never appear in
  any response envelope;
- vault.add validates via VaultStore.add_item and surfaces clean,
  secret-free error messages;
- vault.remove reports {removed: bool} idempotently.
