fanyang b37c1539e1 docs: update bench/007 with hotpath observer effect finding ...

Key finding: hotpath profiling adds 54-57% overhead to benchmarks.
Real production pps (without hotpath):
  Ring: 1,105K pps (12.4 Gbps)
  TCP:  984K pps (11.0 Gbps)

Added gotcha #15 documenting the observer effect, updated benchmark
tables to show both hotpath/non-hotpath numbers, and noted that
timing data should be calibrated by ~2.3x for real-world estimates.
