fix: upgrade Claude AI workflow to ai-workflows@v2.0.0 (#34987)

## Summary

- Upgrades `ai_claude-orchestrator.yml` from `ai-workflows@v1.0.0` to
`@v2.0.0`
- Migrates breaking input changes from the `claude-code-action@v1` GA
release
- Validated and working in `dotCMS/core-workflow-test`

## Changes

| Before | After |
|--------|-------|
| `direct_prompt:` | `prompt:` |
| `allowed_tools:` (multiline list) | `claude_args:` (CLI flag string) |
| `@v1.0.0` | `@v2.0.0` |

## Test plan

- [x] Validated in `dotCMS/core-workflow-test` — automatic PR review and
rollback safety check both passing
- [x] Verify interactive (`@claude`) mention works on a PR in this repo
(Fails cuz it has to be in main before it works)
- [ ] Verify automatic review fires on a normal PR
