Teknium b4ceb541a7 fix(terminal): preserve partial output when command times out (#3868)
When a command timed out, all captured output was discarded — the agent
only saw 'Command timed out after Xs' with zero context. Now returns
the buffered output followed by a timeout marker, matching the existing
interrupt path behavior.
