fix(bump): align output messages with Composer output

- "Nothing to bump." → "No requirements to update in <path>."
- "N constraint(s) bumped successfully." → "<path> has been updated (N changes)."
- Dry-run now shows "<path> would be updated with:" followed by
  " - require.<pkg>: <ver>" per change, matching Composer's format
- Also update bump message in update command for consistency
