## Message

```
agent: Fix mention completion sometimes not dismissing on space (#37922)

Previously we would still show a completion menu even when the user
typed an unrecognised mode with an argument,
e.g. `@something word`.
This PR ensures that we only show the completion menu, when the part
after the `@` is a known mode (e.g. `file`/`symbol`/`rule`/...)

Release Notes:

- Fix an issue where completions for `@mentions` in the agent panel
would sometimes not be dismissed when typing a space
```
