feat(cli): restore IDE grouping using groupMultiselect

Replace flat multiselect with native @clack/prompts groupMultiselect
component to restore visual grouping of IDE/tool options:
- "Previously Configured" - pre-selected IDEs from existing install
- "Recommended Tools" - starred preferred options
- "Additional Tools" - other available options

This restores the grouped UX that was lost during the Inquirer.js
to @clack/prompts migration.
