## Changes

### PR [#2082](https://github.com/danielmiessler/Fabric/pull/2082) by [cp89cyber](https://github.com/cp89cyber) and by [ksylvan](https://github.com/ksylvan): Add `--print-prompt` prompt export mode

- Added a new `--print-prompt` flag that renders the composed chat messages and exits without calling a model.
- Reused the shared message formatting logic so dry-run and prompt export produce consistent output.
- Added validation, documentation, and tests for the new prompt export mode.
- Rejected `--print-prompt` when combined with `--workflow`, returning an error consistent with `--dry-run` and `--output-session`.
- Translated the `--print-prompt` help text and error messages across all 11 non-English locales.
- Changed the `--dry-run` role headers from lowercase (`user:`, `assistant:`) to capitalized (`User:`, `Assistant:`) to match the prompt export format.
