Summary

This PR removes all deprecated code from the Inquirer.js codebase as part of preparing for the next major release.

Breaking Changes

This PR removes the following deprecated APIs:

1. list prompt alias → Use select instead
2. theme.helpMode property → Use theme.style.keysHelpTip(() => undefined) to hide help
3. config.instructions property → Use theme.style.keysHelpTip(...) for custom help text
4. cancel() method on prompt return types → Use AbortSignal in context options
