// Regression for a transcript bug: some providers capture shell output via a
// real terminal session whose input echo - rendered behind a "$ " shell
// prompt - is concatenated directly onto the real output, so the persisted
// stdout opens with a verbatim repeat of the command the chat already
// renders above the Output disclosure. The ACP shell-output normalizer
// strips that leading echo (unit-tested in shell_output_test.go); this file
// drives the mock-agent through the real ACP pipeline and asserts the chat
// UI never shows the command twice.
