docs: go-libp2p v0.49.0 + boxo v0.42.1 - #11410

Picks up webtransport-go v0.11.1 and quic-go v0.60.0 through go-libp2p v0.49.0. webtransport-go v0.11.1 fixes CVE-2026-57497, unbounded buffering of unknown WebTransport capsules, which a peer could use to exhaust memory on any node with WebTransport enabled. Kubo enables it by default. v0.11.x also speaks WebTransport draft-15, so the server answers both the current browser handshake and the newer one Firefox is implementing. The tradeoff is that kubo can no longer dial peers running older go-libp2p over WebTransport. Those peers can still dial kubo, and go-to-go connections use /quic-v1 anyway.

Reframe the webrtc-direct and WebTransport highlights around keeping browser retrieval working, and add the user-visible 0.49 fixes the changelog missed: - confirmed /webrtc-direct address dropped on the shared UDP port - Safari 26.4+ WebTransport handshake requirement - go-to-go WebTransport dial regression - relay backoff after losing a working relay, two shutdown races - quic-go HTTP/3 trailer CVE-2026-40898 in the security section
Moves the pin from a pre-release commit to the tag; the only commits between them are boxo's own go-libp2p v0.49.0 upgrade and release mechanics. Changelog: note the v0.42.1 fixes (IPv6 HTTP providers, shorter /routing/v1 stale windows) and the default CAR traversal depth cap of 1024 the gateway now inherits.
