Missing timeout on Claude CLI subprocess causes indefinite hangs

Location

src/supervisor/executor.py:169

Description

engine.py line 464 has a 900 second (15 min) timeout for Claude CLI, but there's no timeout for the SSH connection test in executor.py line 213 when test_connection() is called with timeout=15. If the SSH connection hangs during the initial multiplexing setup (line 169), it will block indefinitely despite the 15s timeout parameter because setup_multiplexing() only times out the echo command, not the initial connection establishment. This can cause runs to be stuck in RUNNING state until the 4-hour stale run recovery kicks in. Should add ConnectTimeout to SSH options and enforce timeout at the process level.
