Adds tool instalation to the CLI (#106)

### Description
This PR enhances the KaibanJS CLI by including `@kaibanjs/tools`
installation during the KaibanJS installation process. The installation
function now installs both `kaibanjs` and `@kaibanjs/tools` packages,
providing users with a more complete setup experience.

### Changes
- Modified `installKaibanJS` function in `xscripts/cli.mjs` to install
`@kaibanjs/tools` along with `kaibanjs`.
- Updated spinner and error messages to reflect the change.

### Impact
This change simplifies the installation process by automating the setup
of essential tools alongside KaibanJS.

### Test Plan
- Verified that running the CLI with the modified install command
installs both `kaibanjs` and `@kaibanjs/tools`.
