Update SandBase CLI install command to verified v0.1.17 release

The existing SandBase CLI entry is accurate, but its install line currently points to npm `latest`, which still serves v0.1.14 while tokenless trusted publishing is being configured.

Please replace:

```sh
npx -y @sandbaseai/cli connect
```

with the immutable verified release command:

```sh
npx -y https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz connect
```

It would also be accurate to mention that the current catalog contains **25 client targets**.

Verification:
- https://github.com/sandbaseai/cli/releases/tag/v0.1.17
- https://github.com/sandbaseai/cli/blob/main/llms-install.md
