feat: add --verbose flag to run command for debugging

[davidturnbull]

Overview

• Adds --verbose to run to print detailed JSON of translation data and chunks during processing.

Behavior

• With --verbose, the CLI prints:
  • The processable keys/data for each bucket and locale (after filtering/delta checks).
  • Each processed translation chunk before it is merged.
• Output is formatted JSON and intended for debugging. No behavior changes to translation logic.
• Works with existing filters and flags (e.g., --bucket, --file, --target-locale).

Usage

• lingo.dev run --verbose
• lingo.dev run --verbose --bucket json --file messages.json
