fix(connect): trust direct path on peer report timeout

When peers are on different relays, MediaPathReport can't be
forwarded — causing a 3s timeout and false relay fallback even
though direct P2P works perfectly.

Fix: on timeout, if local_direct_ok is true AND the direct
transport's connection is still alive (no close_reason), trust
the direct path instead of falling back to relay. The timeout
indicates a relay forwarding issue, not a direct path failure.

Also fix ALT build paste URL (paste.tbs.manko.yoga not amn.gg).
