flow test prints unreadable output

Comienza ejecutando flow test con el escenario fallido de orden de despliegue mostrado en cadence/tests/yield_vaults_strategy_vault_test.cdc; después, sigue la ubicación indicada en helpers/deployment_helpers.cdc:52. El trabajo estará terminado cuando los fallos de las pruebas ya no emitan el wrapper interno de Cadence escapado, un padding excesivo ni una salida de error sin procesar ilegible.

Summary

When a Cadence test deploys contracts in the wrong dependency order or similar issues, flow test prints hundreds of lines of raw, unformatted output that is nearly impossible to read and lags the terminal.

Current Behavior

The CLI outputs the full internal Cadence representation of the error, including the I.Test.Test.Error(message: "...") wrapper with all nested error chains encoded as an escaped string. Every line of the output is also padded with trailing spaces to a fixed column width. Example:

• thousands of whitespaces, which need text wrapping lagging the terminal
  The output frequently exceeds 200 lines for a single assertion failure.

Expected Behavior

The CLI should display only the actionable Cadence errors (compiler/checker errors, type errors, etc.) with their source locations, without the [Error Code: 1101] transaction wrapper, the cannot deploy invalid contract outer block, or the raw I.Test.Test.Error(message: "...") encoding. Example:

❌ Test Error: cadence/tests/yield_vaults_test.cdc
Assertion failed at: helpers/deployment_helpers.cdc:55:4

error: cannot find declaration `FlowYieldVaults` in `0000000000000007.FlowYieldVaults`
 --> 0000000000000007.FlowYieldVaultsAdmin:1:7

error: ambiguous intersection type
  --> 0000000000000007.FlowYieldVaultsAdmin:23:62

Steps to Reproduce

1. Write 2 contracts
2. A includes B
3. deploy A
