/**
 * Bridges Mushi reports to Sentry's `UserFeedback` channel. Activated by
 * calling [install] after both `SentrySDK.init` and `Mushi.init` have run.
 *
 * Sentry is a `compileOnly` dep so consumers who don't use Sentry pay no
 * APK cost. The bridge resolves the Sentry classes via reflection and
 * silently no-ops if Sentry is missing on the runtime classpath.
