Subject: [PATCH] Fully cut over to tokio

Cut over to notify@0.5.0-pre.11. Much more simple interface, and works
quite nicely with the async ecosystem.

Cut over to axum for web server. Much better!

The updated server stack is now more intelligently handling 404s. This
is a common issue where users may end up making a request for some
non-html static asset, but they get their path slightly wrong and are
served the index.html instead of a 404.

This typically results in users struggling to find the problem, and
often times users have opened issues in GH. This updated algorithm will
now evaluate 404s more closely and only respond with the index.html when
the `accept` header allows for text/html or */*.

Added an example demonstrating all proxy functionality.

+## 0.13.0
+- Trunk has been fully cut over to Tokio@1.x.
+- As part of the Tokio cut over, the Trunk network stack is now fully based on Axum.
+- All download utilities have been made fully async. This will likely help us in the future as we continue to leverage this functionality more and more.
+- Added a new CLI option `trunk clean -t/--tools` which will optionally clean/remove any cached tools used by Trunk, such as `wasm-bindgen` & `wasm-opt`. This may be useful if there are ever issues with old tools which need to be removed.
+- Fixed [#198](https://github.com/thedodd/trunk/issues/198) which was a long-standing issue with the static file server. In essence, Trunk will now check the `accept` header of any `GET` request matching the static file server, and if the requested asset does not exist and the `accept` header allows either `*/*` or `text/html`, then return the `index.html`.
+    - This is expected functionality for SPAs which are using client side routing.
+    - This reduces the friction which has often been observed with Trunk where a user is expecting a 404 to be served when requesting a static image, CSS, or some other asset. With this update, 404s will now be returned as expected, and the `index.html` should only be returned for applicable cases.
+- Added a new `proxy` example which demonstrates all functionality of the Trunk proxy system.
+- Fixed [#209](https://github.com/thedodd/trunk/issues/209) where the default Rust App pipeline was causing wasm-opt to be used even for debug builds when the Rust App HTML link was being omitted.
+- Closed [#168](https://github.com/thedodd/trunk/issues/158): RSS feed for blog.

+Trunk Proxy
+===========
+An example demonstrating how to use the Trunk proxy system for various HTTP endpoints as well as WebSockets.
+
+There isn't much going on in this example as far as WASM is concerned, but have a look at the [`Trunk.toml`](./Trunk.toml) in this directory for exhaustive examples on how to configure and use Trunk proxies.
+
+## Setup
+First, in a shell terminal, execute `docker compose run --service-ports echo-server`. This will start an echo server container which we will use as a generic backend for the proxies we've defined in this example.
+
+Next, in a different shell tab or window, execute `trunk serve`. This will build the demo application and will ultimately start the Trunk proxies defined in the [`Trunk.toml`](./Trunk.toml).
+
+From here, use cURL, xh, websocat or any other tool you would like to verify the proxies' functionality. All normal HTTP requests will be echoed back, and all WebSocket messages will be echoed back.
