Subject: [PATCH] CLI: fail fast if `--context-repo` does not have a matching
 name (#4919)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes CODY-2947

Previously, the CLI would silently continue even if `--context-repo` had
a spelling or referenced a repo that doesn't exist on the instance. Now,
the CLI fails fast with a helpful error message.


## Test plan

Manually tested.
```
❯ pnpm agent chat --context-repo sourcegraph/cody --context-repo github.com/sourcegraph/jetbrains -m 'what is the agent'
...
 ✖ The repository sourcegraph/cody does not exist on the instance. The name needs to match exactly the name of the repo as it appears on your Sourcegraph instance. Please check the spelling and try again.
```
<!-- Required. See
https://docs-legacy.sourcegraph.com/dev/background-information/testing_principles.
