设备会话扩展

设备会话用于可选扩展读取当前已认证设备的身份并提交业务设置，不暴露 access token。

fun BimImManager.registerDeviceRegistrationContributor(
    contributor: BimDeviceRegistrationContributor
)
fun BimImManager.unregisterDeviceRegistrationContributor(
    contributor: BimDeviceRegistrationContributor
)
fun BimImManager.addDeviceSessionListener(listener: BimDeviceSessionListener)
fun BimImManager.removeDeviceSessionListener(listener: BimDeviceSessionListener)
fun BimImManager.getDeviceSettingsSession(): BimDeviceSettingsSession?
suspend fun BimDeviceSettingsSession.updateSettings(settingsJson: String)

val session = BimImManager.getInstance().getDeviceSettingsSession()
session?.updateSettings("{\"notification_enabled\":true}")
println(session?.identity?.deviceId)

BimDeviceRegistrationContribution 只允许提交一个 JSON 对象形式的 settingsJson 和可选厂商标识。设备会话会随登录、退出、token 失效、被踢和 release 变化；调用方不得缓存并跨会话复用。
