/// Install the process-wide rustls [`CryptoProvider`] (ring), idempotently.
///
/// rustls 0.23 builds no TLS config until a provider is selected. It *can*
/// auto-pick one from crate features, but only when exactly one of rustls'
/// `ring`/`aws-lc-rs` features is enabled in the final binary's dependency
/// closure. huddle-core pulls rustls via tokio-tungstenite's `wss://` door
/// without a provider feature, so before this fix only the TUI worked (it
/// enables `ring` transitively through `ureq`); huddle-gui's `wss` worker
/// thread panicked at startup. We now depend on rustls' `ring` directly and
/// install it here, so every consumer is deterministic regardless of which
/// other crates happen to be in the closure.
///
/// Called at the top of the [`AppHandle`](crate::app::AppHandle) start path,
/// before any transport door builds a TLS config. Safe to call repeatedly —
/// a second call (or one racing a transitive dep's install) is a no-op.
///
