+feat: enable WARP (SPED + SNAP) by default, gated by the server
+
+WARP is now always enabled on the client and negotiated with the SFU: SPED
+(DTLS-in-STUN) via the `WebRTC-IceHandshakeDtls` field trial, and SNAP
+(SCTP-INIT-in-SDP) via the `RtcConfiguration.enable_sctp_snap` field. When the
+server does not enable WARP it is not advertised and the connection falls back to
+plain DTLS/SCTP, so there is no client-side toggle.
+
+BREAKING CHANGE: `libwebrtc::RtcConfiguration` is now `#[non_exhaustive]` and has a
+new `enable_sctp_snap` field. Construct it from `RtcConfiguration::default()` and set
+the fields you need instead of a struct literal.

 ## [Unreleased]
 
-### Breaking
-
-- `RtcConfiguration` is now `#[non_exhaustive]` and gained an `enable_sctp_snap` field
-  (WARP / SNAP — SCTP-INIT-in-SDP). Construct it from `RtcConfiguration::default()` and
-  set the fields you need instead of a struct literal; future fields can then be added
-  without a breaking change.
