Preserve raw output across polls.

ProcessManager.Continue returns raw output collected since the previous poll. A chunk can end in the middle of a line. The inserted newline can split listening from the address, so parseListeningAddress can miss the address until the 20-second deadline.

🐛 Suggested fix 
-output += "\n" + poll.Output
+output += poll.Output
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
output += "\n" + poll.Output
output += poll.Output

Review comment at @internal/tools/exec_command_test.go at line 394:
Update the poll-output accumulation so it appends `poll.Output` directly to
`output` without inserting a newline, preserving raw chunks across polls for
`parseListeningAddress`.
