ginuerzh 3f671abfb6 fix(ssu): prevent goroutine/connection leak in UDP session cache ...

The ssuHandler's connMap cached UDP forwarding connections but spawned
goroutines had no context cancellation mechanism. When relayPacketUDP
exited (e.g. on SS UDP session timeout), orphaned goroutines blocked
indefinitely on ReadFrom, preventing connMap cleanup and leaking both
goroutines and connections.

Fix: derive a cancellable context in relayPacketUDP so all per-session
goroutines are cancelled on exit. Add SetReadDeadline with 30s periodic
timeout so goroutines can check context cancellation instead of blocking
forever. Store cancel functions in a cancels sync.Map for cleanup.

Fixes #821
