<content type='text'>
We no longer need to clone `CongestionWindowParams` now that it
implements `Copy`.

Resolves a clippy warning.

These will likely always just be a collection of integers (lightweight
to copy).

First, run

```
git grep -l "^edition =" |
    xargs perl -i -pe 's/^edition *=.*/edition = "2024"/;'
```

Second, manually verify that all Cargo.toml files have changed,
and nothing else has changed.

Third, run cargo fmt again.

Instead call it compatible_with_cgo, which is what we actually
care about in this context.

This doesn't really change anything, but removing the `.clone()` makes
it a bit more obvious that copying the `*Params` is a lightweight
operation.

The fallback CC algorithm is _always_ fixed-window, and we should only
use it when the selected CC algorithm is not supported.

<id>urn:sha1:11fe4bb4d74e4f936bc360f6b5c5cf539e94b99c</id>
<content type='text'>
Now tor-circmgr no longer needs to check which Protover capabilities
are enabled, or construct a separate CircParameters for each hop.
Instead, tor-proto decides whether to use the fallback CC mode,
based on whether the target supports FLOWCTRL_CC.

Closes #1967.
