/**
 * Opt-in diagnostic logging.
 *
 * The library previously called console.log directly in 36 places across the
 * signaling, WebRTC and middleware paths. That is useful while debugging a
 * connection and unacceptable in a dependency: an application embedding this
 * had its console filled with `[roomListenerMiddleware] setRoom: {...}` on
 * every room change, with no way to turn it off.
 *
 * Diagnostics are kept — they are genuinely hard to reconstruct after the fact
 * — but silent unless asked for. Errors and warnings still go out
 * unconditionally through console.error/console.warn; those are for the
 * application, not for us.
 *
 * Enable at runtime:
 *   p2party.setDebugLogging(true)
 *
 * or persistently, before the library loads:
 *   localStorage.setItem("p2party:debug", "1")
