Workaround for panic due to missing global validation in clap (#14368)

Browse source 
Clap does not perform global validation, so flag that are declared as
overriding can be set at the same time:
https://github.com/clap-rs/clap/issues/6049. This would previously cause
a panic. We work around this by choosing the yes-value always and
writing a warning.

An alternative would be erroring when both are set, but it's unclear to
me if this may break things we want to support. (`UV_OFFLINE=1 cargo run
-q pip --no-offline install tqdm --no-cache` is already banned).

Fixes https://github.com/astral-sh/uv/pull/14299

**Test Plan**

```
$ cargo run -q pip --offline install --no-offline tqdm --no-cache
  warning: Boolean flags on different levels are not correctly supported (https://github.com/clap-rs/clap/issues/6049)
    × No solution found when resolving dependencies:
    ╰─▶ Because tqdm was not found in the cache and you require tqdm, we can conclude that your requirements are unsatisfiable.

        hint: Packages were unavailable because the network was disabled. When the network is disabled, registry packages may only be read from the cache.
```
