sdk/io/io-ktor/src/commonMain/kotlin/app/meetacy/sdk/io/InputIntegration.kt:30:13 'attachJob(Job): Unit' is deprecated.

in the last build log from #102, I saw `sdk/io/io-ktor/src/commonMain/kotlin/app/meetacy/sdk/io/InputIntegration.kt:30:13 'attachJob(Job): Unit' is deprecated` line. `attachJob(Job): Unit` will be removed with Ktor 4.0.0 release. let's prepare for the future upgrade.
