Subject: [PATCH] :sparkles!: add async-trait dependency for WebAppExt trait
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add `async_trait` as an optional依赖ency in pmoapp/Cargo.toml
- Enable usage of `#[async_trait]` on WebAppExt trait and its impl for Server
- Guard async-related code with `#[cfg(feature = "pmoserver")]`
