- Add NewLimiterWithBurst(rate, burst) for independent burst control - Extend parseLimit to accept optional 4th field as burst size - Add DroppedPacketCounter interface with DroppedPackets() for packet/udp conns - Export ErrRateLimited sentinel for rate-limit error checks - Fix IP-level cache expiration (NoExpiration → defaultExpiration) to prevent unbounded growth; reset TTL on access in In/Out - Short-circuit single-limiter path to avoid limiterGroup allocation - Add nil guard in cachedTrafficLimiter when both old and new values are nil - Remove unused ctx field from wrapper structs
