### Summary

Direct user feedback asks for more control over `vp up` output formatting and organization.

### Requested improvements

- Group output by pnpm catalog, similar to `taze`
- Allow customizing visible columns
- Allow controlling line wrapping

### Why this matters

Users comparing dependency update tooling expect better readability and output control, especially in larger workspaces.

The issue names the `vp up` entry point but no files or tests. Start by locating its output-generation code and comparing the current behavior with the requested catalog grouping, column selection, and line-wrapping controls. Done requires agreed behavior and coverage for each customization.
