Self checklist

• I have titled my PR with Region | Cohort | FirstName LastName | Sprint | Assignment Title
• My changes meet the requirements of the task
• I have tested my changes
• My changes follow the style guide

Changelist

• Add cat/cat.js scaffold with CLI entry (shebang + basic argument parsing).
• Prints a usage message when no args are provided; placeholder output when args are present.

How to test

From the repo root:

# 1) No args -> shows usage and exits with non-zero status
node cat/cat.js

# 2) With any file arg -> shows scaffold placeholder (no functionality yet)
node cat/cat.js cat/sample-files/1.txt

## Questions

I’m new to this — is my commit plan OK? (cat in small steps: scaffold → basic → -n → -b)
