charset=UTF-8 Content-Transfer-Encoding: 8bit Three `.expect()` sites that upstream introduced after the original avoid_panics commit was authored — replace with proper error propagation so the dial/setup paths cannot panic: - `quic/mod.rs` async dial: `make_client_config` failure now returns `QuicError::InvalidCertificate`; `IdleTimeout::try_from` overflow returns `DialError::Timeout`. - `webrtc/mod.rs` transport setup: `Multihash::wrap` on the listener certificate fingerprint propagates `Error::InvalidData` instead of panicking on length mismatch.
