Analyze the repository and recommend 10-20 candidate topics. Topics must be lowercase and hyphenated (e.g., `command-line-tool`, `typescript`).

## Validate topics

For each candidate, verify it exists on GitHub:

```bash
gh search repos --topic=<topic> --limit=1 --json fullName --jq 'length'
```

Drop any topic that returns `0`. Show the user which topics were removed and why.

## Apply topics

```bash
gh repo edit --add-topic topic1 --add-topic topic2 --add-topic topic3
```

Print the final list and a link to the repository.
