fix(test): remove shadowed consoleErrorSpy declarations in on-complete-hook tests

Remove duplicate consoleErrorSpy declarations in 'command failure' and
'spawn error' tests that shadowed the outer beforeEach/afterEach-managed
spy. The inner declarations created a second spy on the already-spied
console.error, causing restore confusion and potential test leakage.
