docs(file): correct compress description and stale file-output references

- Drop the misleading 'under provider upload limits' claim from the compress
  tool description (models cannot read zip archives)
- Fix bestPractices to reference the 'files' output, not a non-existent 'file'
- Remove the stale 'file' property from the compress test fixture so it
  matches the real API response (greptile)
