server: add --connect, allow p2p access to server outside LAN (#28277)

• init

• wip

• wire it up

• make it clear that it's experimental

• add props.connect_code

• nits

• fix windows build

• server: do not advertise a connect code without the tunnel

--connect-code on its own had no effect other than being served in
/props, so the Web UI showed a remote access code that no tunnel was
serving. Clear it when --connect is off, and say so once at startup.

The teardown comment claimed that terminate() closes the child stdout.
It does not: the log thread leaves fgets() only once every writer of
that pipe is gone, so a descendant of llama-connect would block the
join forever. Describe the real contract instead.

Also restore the --reasoning-preserve default in the generated docs.

• Update tools/connect/CMakeLists.txt

• server: dial llama-connect on the bound port and a reachable host

Pass ctx_http.port so --port 0 and the GCP override work, pick the
dial host from --host (wildcards map to loopback, IPv6 is bracketed)
and refuse --connect when only unix sockets are bound.
