MOVZXandHinata 5df639bb4e [QSA] Start the clip-counter reader after capture, not on the first forward
The FP8 KV clip counter's reader thread used to start on the first eager forward, before CUDA graph capture, so
its device-to-host copies could overlap a capture. _qsa_clip_count now only allocates the per-layer counter; the
reader is started by a hook that guard_telemetry runs after warmup and capture (or at once if capture is already
done). Counting is unchanged. Tests cover the order, idempotence and a failing control that restores the old start.
