Closes issue 217. The isPublicUrl input-time guard catches every
RFC1918 / CGNAT / loopback / link-local alt-notation, but a low-TTL
DNS record can flip between accept and dispatch. The new
pinnedPublicDispatcher resolves the hostname literally inside
undici.Agent's connect hook, refuses any address isPublicIp would
reject, and pins the connection to the first valid public address.
The five outbound paths that accept a user-supplied host route
through the dispatcher via safeFetch's requirePublicHost flag —
moodlog sync, moodlog reverse-push, the moodlog credentials probe,
the local AI client (already gated in commit 1), and the ntfy
sender. The flag now buys both the input-time check and the
connect-time pin in one call.

Closes issue 218. Flips the convention from "remember to opt in to
redirect: manual" to "remember to opt out". Every outbound fetch that
doesn't pin a hard-coded host now routes through safeFetch and inherits
AbortSignal.timeout(15_000) so a tar-pit upstream can no longer pin a
worker indefinitely. The local AI client also gates on
requirePublicHost: true since its host is user-supplied; operators
running self-hosted Ollama / LM Studio on an RFC1918 address keep their
escape hatch via ALLOW_LOCAL_AI_PRIVATE_HOSTS=true (also enforced at
write-time in /api/user/ai-provider).
14 outbound call sites migrated. The four that already pinned manual
redirect (the historic templates) keep their semantics; the wrapper
preserves an explicit init.redirect. Adds undici as an explicit
dependency so the connect-time pin landing alongside this can rely on
the documented API rather than a transitive hop.
