sitecustomize.py is imported automatically by Python at startup
in every process, including the SGLang scheduler/TP worker
processes spawned for tensor parallelism. Adding the p800_timing
import here ensures the monkey-patches are applied to all 8 TP
workers, not just the launch_server parent process (which never
runs the model forward and would record empty timing data).
The timing module self-disables unless SGLANG_TIMING_ENABLED=1,
so this import is a no-op when timing is not in use.
