Function pipeOutputLineCount

packages/cli/src/pi-transcript-tools.ts:231–238

* Combined line count for a pipes result. Each stream is counted after * trimming its own trailing newlines and the counts are summed — joining the * streams first would invent a line at the boundary (`out\n` + `err\n` is * two lines, not three).

(output: { stdout?: string; stderr?: string })

 * two lines, not three).
