Subject: [PATCH] test(cli): stabilize acp --help snapshot against random home
 path length

yargs wraps the \`[string] [default: "..."]\` clause based on the
pre-normalized default value's character length, so a different random
tmpdir width produces a different leading-whitespace count on the
wrapped continuation line. After normalizing the path to \`<HOME>\` we
were left with a one-space drift between runs.

Collapse the wrap-dependent whitespace immediately before the clause
so the snapshot is byte-stable regardless of home path length.

Verified by deleting the .snap and regenerating across 3 runs.
