The `expect` attribute is similar to `allow` in that it will silence a
particular lint. In addition to `allow` however, `expect` will fail as
soon as the lint is no longer emitted. This ensures we don't end up with
stale `allow` attributes in our codebase. Additionally, it provides a
way of adding a `reason` to document, why the lint is being suppressed.
On Windows, the network notifier always notifies once at startup. We
make the DNS notifier and Linux match this behavior, and we assert it in
the unit test.
Part of a yak shave towards removing Tauri.
Closes#5063, supersedes #5850
Other refactors and changes made as part of this:
- Adds the ability to disable DNS control on Windows
- Removes the spooky-action-at-a-distance `from_env` functions that used
to be buried in `tunnel`
- `FIREZONE_DNS_CONTROL` is now a regular `clap` argument again

Closes#5846
Will be moved down to the IPC service eventually.
The goal for connection roaming is not for totally transparent "Change
Wi-Fi networks without dropping SSH" handoffs, but just for Firezone to
re-connect itself as quickly as possible so that everything above us can
re-connect as quickly as it times out, and won't be hung up with a
broken tunnel.
Note that for GUI Clients, listening is still done by the GUI process,
not the IPC service.
Yak shave towards #5846. This allows for faster dev cycles since I won't
have to compile all the GUI stuff.
Some changes in here were extracted from other draft PRs.
Changes:
- Remove `thiserror` that was never matched on
- Don't return the DNS resolvers from the notifier directly, just send a
notification and allow the caller to check the resolvers itself if
needed
- Rename `DnsListener` to `DnsNotifier`
- Rename `Worker` to `NetworkNotifier`
- remove `unwrap_or_default` when getting resolvers. I don't know why
it's there, if there's a good reason then it should be handled inside
the function, not in the caller
```[tasklist]
### Tasks
- [x] Rename `*Listener` to `*Notifier`
- [x] (not needed) ~~Support `/etc/resolv.conf` DNS control method too?~~
```
