ginuerzh	79718ee19e	fix(handler/dns): buffer pool leak, write deadline, async error logging, EDNS0 buffer ... Fix bufpool leak when PackBuffer fails by extracting packResponse helper. Add write deadline before conn.Write to prevent goroutine hangs on slow clients. Log async exchange errors instead of silently discarding them. Raise defaultBufferSize from 1024 to 4096 to match EDNS0 standard. Deduplicate lookupHosts TypeA/TypeAAAA branches.	2026-05-26 21:22:19 +08:00
