- Add udpBufferPool for reusable 65507-byte UDP packet buffers
- Add getUDPBuffer() and putUDPBuffer() helper functions
- Clear buffer contents before returning to pool to prevent data leakage
- Apply pooling to both main handler buffer and per-client goroutine buffers
- Reduces GC pressure from frequent large allocations during UDP proxying
Made-with: Cursor
- Add maxUDPPacketSize constant to replace magic number 65507
- Remove commented-out code in Stop()
- Replace deprecated ne.Temporary() with errors.Is(err, net.ErrClosed)
- Use errors.As instead of type assertion for net.Error
- Use errors.Is for closed connection checks instead of string matching
- Handle closed connection gracefully when reading from UDP target
