fix(ssrf): Telegram media download IPv4 fallback regression from 45b74fb56c
증상
Telegram media downloads (PDFs, images, voice, etc.) fail with TypeError: fetch failed → AggregateError [ETIMEDOUT] in dual-stack environments where IPv6 is enabled but has no internet route (common in Docker/container deployments).
원인
Container permission, networking, or environment variable misconfiguration inside the sandbox.
해결법
createPinnedDispatcher should default to autoSelectFamily: false. Pinned dispatchers pre-resolve DNS via resolvePinnedHostnameWithPolicy() and dedupeAndPreferIpv4(), making Happy Eyeballs address selection redundant. Setting autoSelectFamily: false prevents IPv6-first connection attempts that timeout before IPv4 can succeed.
Also extends createPinnedDispatcher to accept optional connectOptions for callers that need explicit control over address family selection.
