* Upload debug files to both Sentry projects

Apparently it's not possible to share debug files cross projects. So let's upload to both of them. To one we use in production and one we use for testing.

* Use environment variable

* Reclaim disk space only in the very end of `tart clone`

Please check comments in code for reasoning.

* Phrasing

* Removed hidden argument

* Allow mounting a single directory without a name

To utilize `VZSingleDirectoryShare` which seems more stable than `VZMultipleDirectoryShare`.

We've been having reports from users that mounted directories occasionally return "no such file" errors when building large projects. I took a stab at reproducing the issue by running https://github.com/devMEremenko/XcodeBenchmark in a mounted directory:

```bash
tart run --dir=workdir-test:~/workspace-temp/XcodeBenchmark ventura-xcode
```

And I was able to reproduce the "no such file" error on the first try! After looking into the issue I decided to try `VZSingleDirectoryShare` as this PR changes and to my pleasant surprise it all worked like a charm the next run. So it seems there is a bug in `VZMultipleDirectoryShare` integration with virtiofs. Since in most cases users only mount a single directory it makes sense to allow doing it wihtout providing a `name`.

So now it will be possible to run the following command:

```bash
tart run --dir=~/workspace-temp/XcodeBenchmark ventura-xcode
```

Which will make `~/workspace-temp/XcodeBenchmark` available under `/Volumes/My Shared Files/` without any intermediate directories.

* Reformat
