The URL test history update hook and the Clash mode update hook were
single-slot: the API service's attached service overwrote the hook set
by the daemon, so clients stopped receiving group updates. Replace both
with multicast hook lists.
Also share a single URL test history storage via context: Clash API
looked it up under a key nobody registered and fell back to its own
empty storage, so dashboards showed no delay once an API service was
configured. Selector changes now notify through the shared storage,
covering selections made from any API surface.
We mistakenly believed that `libresolv`'s `search` function worked correctly in NetworkExtension, but it seems only `getaddrinfo` does.
This commit changes the behavior of the `local` DNS server in NetworkExtension to prefer DHCP, falling back to `getaddrinfo` if DHCP servers are unavailable.
It's worth noting that `prefer_go` does not disable DHCP since it respects Dial Fields, but `getaddrinfo` does the opposite. The new behavior only applies to NetworkExtension, not to all scenarios (primarily command-line binaries) as it did previously.
In addition, this commit also improves the DHCP DNS server to use the same robust query logic as `local`.
