What's in this release

• fix: phantom request accumulation in cache_aware load tracking #23 — fix: phantom request accumulation in cache_aware load tracking
  • Removes the retry-path double-decrement of the per-worker load counter
  • Adds a 300s inactivity timeout on the SSE streaming forwarder
  • Unblocks cache_aware and power_of_two routing policies that depend on an accurate per-worker load counter
• treat vLLM input validation 500s as 400 for circuit breaker #24 — treat vLLM input validation 500s as 400 for circuit breaker
