fetcher binary doesn't build

[molenick]

Reproduction steps:

1. Clone repo
2. cd async-fetcher/fetcher
3. cargo run

Result:

-> % cargo build
warning: method `content_length` is never used
   --> src/lib.rs:651:8

    = note: `#[warn(dead_code)]` on by default

   |     ^^^^^^^^^^^^^^^^^^^^^^^^ no `Shutdown` in the root

Is this binary still being maintained?

I noticed that there's no CI workflow that proves this crate can be built, could be good to add one + run tests
