Bumps github.com/getlantern/radiance to the suppress-ipv6 branch (getlantern/radiance#517), which suppresses IPv6 inside the tunnel so applications fall back to IPv4.

Why

On global-IPv6 networks, AAAA traffic for dual-stack sites was routed onto a v6 path that stalled with no fallback — surfacing as an endless spinner (e.g. YouTube video that never plays) while connected.

What the bump brings (radiance)

  • DNS: only A queries route to the fake-IP server; AAAA is answered with NODATA (NOERROR + no records) so clients see no v6 address and use IPv4.
  • Routing: all IPv6 destinations (::/0) are rejected with the default method (ICMP unreachable / RST → Happy Eyeballs fails over to IPv4 at once), as a backstop for v6 that escapes AAAA suppression. Gated on the TUN having captured a v6 address.

Note

Points at a radiance branch commit, not main. Depends on getlantern/radiance#517 — once that merges, re-bump to the resulting main pseudo-version before merging this.

Got to revert this — apparently some networks require IPv6.
