security: verify PID belongs to claude before SIGKILL (#160)

Add _is_claude_process() that reads /proc/{pid}/comm to confirm the
process is "claude" or "node" before sending SIGKILL, preventing the
kill from hitting an unrelated process if the original claude pid was
recycled by the kernel between cron ticks.
