Introduces support for Gerrit-style magic push references via
`refs/for/<branch>`. Pushing to this ref automatically extracts the
target branch and opens a patch against it, bypassing the need for the
push option `patch.target`. Example:
```
$ git push rad HEAD:refs/for/accepted
```
Will open a patch with its `patch.target` set to `refs/heads/accepted`.
When invoked without any of `--patch`, `--delete`, `--accept`,
or `--reject`, the command panicked.
It will now correctly return an error to use `--accept`, `--reject`,
or to supply a message.
Note that `--patch` and `--delete` are removed as these commands are
now obsolete.
The new doc test also documents two previously-untested behaviors
of `rad patch review`: neutral reviews (verdict=None with summary)
and the COB layer's silent no-op when a duplicate review is submitted
(see `test_patch_review_duplicate` in radicle-cli/tests/commands/patch.rs).

Exercise the edge case where Bob, as a delegate, has never pushed to the default branch.
He then merges Alice's patch, and it is correctly marked as merged.
