fanyang 2794b96028 docs: re-align bench/007 with origin/main baseline (no hotpath) 
Measured true baseline from origin/main worktree (+ bench + loopback fix):
  Ring: 293K → 1,124K pps (+284%)
  TCP:  298K → 975K pps (+227%)
  UDP:  630K → 1,066K pps (+69%)

Updated all tables with calibrated numbers. Restructured optimization
table to show real impact ranking (noop_waker as core breakthrough).

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.
