[FEATURE] Include Model Name in `UserPromptSubmit` Hook

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

I'd like for the currently selected model to be included alongside the prompt in the UserPromptSubmit hook (https://code.claude.com/docs/en/hooks#userpromptsubmit).

This would let me:

• Block execution & suggest a different model based on the prompt or an approved list of models
• While audit logging, allow me to see which prompts were issued to which models

Proposed Solution

There's a new "model" property included in the hook with a string identifying which model Claude Code is currently running with.
