ginuerzh 64f9a048f8 feat(limiter/traffic): add burst support, dropped-packet counters, and cache fixes ...

- 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
