Changes

test(proxy): fix flaky TestShadow timing and counter assertions (#4327)

Summary

Fixes non-deterministic failures in TestShadow caused by rigid timing
thresholds & Vegeta request count variance under CI load

Changes

1. FIFO Shedding Assertions: Replaced the rigid statusFifoFull < 2
   check with cumulative capacity validation (statusFifoFull + statusFifoTimeout >= 10 and statusFifoTimeout >= 1) to account for
   sub-millisecond inter-arrival timer drift and wait timeouts under heavy
   CPU load
2. Request Count Tolerance: Decoupled success validation from strict
   nominal target equality ($N = 100$), comparing statusOK and
   counterMain against completed requests (reqCount with a tolerance
   bound of reqCount >= N-5) to prevent false-positive failures due to
   attack timer truncation
